PERFECT for the Cross Country Rally run!!   Keep in mind something about the AOD trans. You cannot use WOT in OD of the AOD, it will drop down to 3rd gear at high throttle, to save the weak OD band. So figure out what your top speed will be based on the 1:1 3rd gear ratio. Use OD to cruise with, I'm not sure at what high speed the OD would realize too much load and slip. If you can do it, find a reputable AOD builder who has done internal upgrades on an AOD. The AODE had a wider OD band, and the three required parts from those will directly swap into the AOD. Install a much bigger OD servo set(three parts), aftermarket. That's the holding power for the 4th gear. Bauman had a shift kit which included a certain spring which was supposed to force the AOD to stay in OD at WOT. Do that at a certain risk, running in 3rd gear is much safer for the trans, even though the direct clutches are the second weakest link. http://www.becontrols.com/aode.htm Baumann's 4R70W page

I would suggest going with the 4R70W, which has everything good from upgrades of the AOD and AODE. The 4R70W is the fully upgraded descendent of the AOD, the 98 having the last big worthy improvement(mechanical diode). Those are very strong, the AOD is questionable in any stock form, weak in most.

Ran by a buddy's house today to talk about some parts for the Rally Car.Well, he bought this for the motor & tranny.

Yep, but I think I have a different body shape in mind, a little, flatter should I say.

if you straighten that out, you will definitely be a master body man! 

I think its a job for Malcolm.

Trip to the Torino farm today with David Ryland (from FB, he lives in Wichita) he brought me 5 more magnum 500 rims and 2 14" US Indy slots with center caps. We went to the farm, he got the seats from Ol'Brown and a 73 rear bumper.

we spent time looking over Brown and the others.

Thought was to use Brown for the Rally car.
get the blue 73 running and sell it....
NOPE, Brown just needs to much to be roadworthy and Bonnie needs too much engine work.
But Bonnie is solid and will now be the base ffor the rally car.
Andy is coming down to get the engine/tranny from Bonnie.
David wants the 73 nose stuff too.

I'll get a 72 nose on her and she is the Rally car!
Guess i got some work to do.

I BELIEVE 1981 was the last year for the 9" in pickup and bronco.  Not that someone couldn't have swapped it out.

A lot of Broncos were optioned with 31 spline traclok carriers that's why I asked.
