15x7 5x5.5 bolt pattern

Thanks, so no acorn style then?

You will also have to find out how long the shanks have to be on the lug nuts. And you will probably have to find out what shank size width that you will need.  

Some shank style lug nuts use washers with a centered hole in the middle. Like in the picture below. The washers are used to keep the wheel centered while you are tightening the lug nuts.

Below is a picture of the bumps inside the of lug nut holes on the wheels (your wheels might be different though). As you hand tighten the shank lug nuts, the bump(s) or tab(s) on the offset washers, will come to a stop and seat themselves on the bumps or tab(s) inside of the wheel lug nut hole, and it will center the wheel onto the lugs.

When you install the "offset hole" washers, the washers will stop on the bumps or tab(s) while you are hand-tightening the shank lug nuts. The washers should be in the same position as in the picture below.

You should also measure how long your lugs are at the front brake rotors (or front brake drums), and you should probably measure how long the lugs are at the rear brake drums. It might be better to measure them with the wheels off of the car.

You can see from the picture that they are not oblong or oval shaped or circular. So do I have to find washers to fit those exact wholes or could I use a circular ones that fit the slots?

Here is a picture of weaverT1971's wheel below.

That is good news.

no name just a patent number....that goes back to the old ET wheels.

DO NOT use round washers on wheels with the oblong recesses. Bad things WILL happen. Only use the oval/oblong wheels with those wheels.

So, are you gonna leave these new wheels on the '71, when you trade it for a '72?  Or, keep them for the '72?  Seems like a lot of trouble if you're gonna include them with the trade.

Well.....I got the wheels and tires.....and the correct lugs and the washers.....BUT the 275's are to wide. they wont clear the fender wall, I mean seriously these would barley fit inside the wheel well. Now I'm really confused because I looked on here and found posts of guys throwing these on their cars with no issues at all. I guess I must've not measured the back spacing correctly...it seems if the rims were deeper they would work but.....So what are my options at this point to get these to fit on my car? Leaf blocks, air shocks? http://www.fordmuscleforums.com/torino-pages/424920-largest-wheel-tire-size-combination-72-gran-torino-sport-fastback.html

So what can I do? But really though I don't think that really has anything to do with it. It just seems that if the rims were deeper they would clear. there's plenty of room in the wheel well on the top and it's not hitting anywhere else besides the outer wheel well.
