Ah. The Jeeps have the shocks mounted seperately from the springs (big bumpstop at the top of the spring, pocket at the bottom) and I tried inserting it through the spring. Good thing they have solid axles on both ends (loosen a few bolts and the axles drop enough to let the springs fall out/ Leafs on the XJ rears) or it would indeed be dangerous to pry on them. I was just trying to save time - ended up being a fast job when done correctly.

I wonder if a machine shop could make a tapered "extension" for the stock lower ball joint that would allow you to screw the extension onto the original ball joint (with an inside taper to match the outside), and then you would just tack weld it to hold it from unscrewing?
I might order in a stock lower ball joint and take it to a machine shop for their opinion.
If this does not work, then I think I will just go the coilsprings.com route with 1 1/2 inch drop springs.
Will let you all know if the machine shop idea pans out....thanks for the ideas.

Just wondering on the guys who did the Moog 80090 CVPI springs, did you get any settling with time?

I finally got my car back together and it sits at about 27.5". I am hoping it settles a bit after I drive it, but I got to get it into the alignment shop this week.

I don't know if I have had any settling to be honest.
I also installed the matching CVPI shocks.
 
I honestly have not noticed much difference.
Debated about taking half a coil off this winter however.
Shot from about 2 weeks ago.

Andy, I think a 1/2" to 1" drop on the front would be WAY COOL!

Thanks Andy. Well if mine doesn't settle, I may cut half a coil too. My car was sitting at about 26.5" with stock springs, but they were definitely saggy. I just got used to the lower look.

I haven't replaced the rears yet, so maybe when I do them it will improve the stance.

I got my car aligned today and was able to put it throught it's paces it bit. What a HUGE improvement in handling. The CVPI springs with the larger sway bar keeps the car very flat in hard corners. I think the ride is great, better than before. It's defintely firm, but by no means harsh. If anything a late model CVPI seems more harsh. I am sure the Bilstien shocks help with that too, they are excellent.

The rear feels soft now. I am going to try Moog 8531's which are about 183 in/lbs. I know the CVPI's use about 170 in/lbs rear. I don't know what the stock spring rate is, all I know is that they are the HD springs which have a higher load rate than even the stock Competition suspesnion springs. I don't like variable rate springs, so I don't want to run cargo coils. Hopefully these with the new 7/8's sway bar, and Bilstiens, will stiffen up the rear end and slighly lift it.

As for others thinking of Moog 80090, I highly recommend them. Just be warned on a 1972 they will not lower the car at all, so be prepared to trim them if you want to lower the car.

I believe taht the stock rear springs on the GTS is 192 lb/in rate.   However, its variable rate.  From what I calculated from stock compression height...it appears to be average rate of 183 lb/in.
 
 
I think the crown vic's rate is 160 lb/ins, but the tail end is lighter than a fastback gts.

I also did an extensive search for alternative rear springs and didn't find anything.  I found chevy springs but the pigtail is a different size.   I came to the conclusion that if you want different spring rates, constant rate, or change the ride height you will have to order custom springs from:
eatonsprings.com
coilsprings.com
 
The prices I received was about $189 with shipping around $25
 
This is what I decided to do.   Planning constant rate spring about 1" lower and increase the rate to 200 lbs/in approx.

Those CC 801's are cargo coils, and stiffer than stock but like you said variable rate. If you look up the Moog stock 1972 Torino springs it only lists one at 158 in/lbs, 8307. Some later year Torinos used even softer rears, around 144 in/lbs.

We don't know what the factory spring rates are, Ford didn't list them, only the load rates (which is simply the amount of weight the spring is designed to carry). That said, if all else is equal, generally, the only way to get a higher load rate is to have a high spring rate (stiffer spring).   The Police had the highest, followed by the HD springs, followed by the competition suspension, and the lowest were the stock suspension.

Earlier in this thread, I think there is a spread sheet that compares all the aftermarket spring available for our cars. Without going to cargos (varible rate), the stiffest you can get from the aftermarket replacement springs is about 183 in/lbs.

Ol' Brown's Resurrection is contributing to the Coil Spring Thread...
 
Moog CC819 rear coils will NOT work on a 72!
The top and bottom pigtails are too tightly wound, they do NOT fit around the spring perches TOP OR BOTTOM.
 
They are REAL CLOSE to the same height uninstalled as the 40yr old stock springs. 16.5"
 
 
But I made some measurements anyway... 
ALL measurements are with 295/50/15 tires and measured ground to center of the wheel well at the bottom edge of the fender lip.
 
Air shocks raised the car 2" with the saggy 40yr old springs.
But when I did let the weight on the new CC819 just to see and measure the air shocks were maxed out even without air! So it may be that with high springs I may need shock extender tops.
 
Old springs with full air shocks at 28"...
CC819's installed and sitting at 29". Man, these things are STIFF!
 
Time to send these back and we'll see what springs to put in from the height/weight numbers in the chart, hopefully they will fit the perches.

So, to add another angle here...

Does anyone know what, specifically, the difference btw the Moog CC801's and the Eaton Torino springs (No Part number) for the rear of a 73 ?  Different dia wire?  Different load rating?

Eaton's are $160 for a set of rears, Moogs go for $80.  Not a huge cost difference, but for $80, it would be nice to know exactly what the difference is.  Maybe its the ability to call Eaton and ask for a stiffer, taller, shorter spring and get what is right for my application (this per their website). 

Thanks !

I have a set of 188# Eaton springs that are 1 1/2" (?) higher than stock. Not sure I'm going to wind up leaving them in though. I have no real weight on the springs aside from the body they seem a bit too high for me.

Pic of the car from the side with these springs?
Maybe a measurement from ground to the fender lip and what tires are you running?

Well, I have do rear springs. Right rear coil is bad.
Also replacing my shocks.

Aside from oem type shocks, what aftermarket monotubes are suggested? I am not impressed with my front shocks I replaced.
Just realize 16+ pages. Thinking time to rework the details.

I'm about to have to contribute to this thread, I think.

Taking the sedan in for a steering/suspension bits quote this afternoon. Also getting that filler neck gasket installed so I can put more than 5-6 gallons of fuel in at a time. I'm expecting a very high quote and I plan to buy some parts at RockAuto to save on that.

If the springs are broken anywhere I intend to replace the fronts with the CVPI ones, Moog 80090s ($65.79 a pair on RockAuto at the moment) and the rears with Moog CC807's (only a dollar more for the pair). I like float, but I want to be able to steer around corners. The CC803's are only $52.79 a pair though, and I'm considering those because I do carry all my tools with me all the time in the sedan.

Shocks I know I need for sure, I'm thinking Monroe all around. Sensa-Trac 58263 Load Adjusting up front and Max Air MA805's out back, that way I can adjust as needed with an air compressor.

I hope they don't have to replace the entire steering system (tie rod outer and inner, upper and lower ball joints, idler/pitman arms, center link), so I can afford to go after all this is done and grab a set of the 16" CVPI steel wheels, trim rings, and some decent H-or-better-speed-rated 225/60R16 tires.

Then I definitely need seats and maybe carpet. Then I'll be ready for HRPT and maybe if I'm lucky I'll have the vacuum leak found by then and it'll fly.

Sway bars will do a lot more to control float vs springs..
