3 questions after searching AOD info

[Rapid]

65 coupe, 289, C4, 6 bolt block, Edelbrock intake and 4bl carb, std diff.

1) Shorten drive shaft or yolk. If yolk, C4 yolk or AOD conversion yolk and how much?

2) If dirve shaft 50 inches?

3) Will the throttle rod set up std with a 289 4bl work with the Lokar AOD kick down?

I will be doing the conversion in January and need to make sure I get it right. Many words are out there and many conflict. If anyone know of the ultimate swap thread, please send me there. I don't want to spend mare than necessary but am more interested in making the project as "bolt on" as possible to save down time on my daily driver.

Thanks in advance.

I bought the AOD conversion kit which comes with a new yolk. I took my driveshaft in today to have the yolks swapped. The guy grabbed the new yolk and measured it. He tool the driveshaft w/old yolk and placed it on a table. Before I knew he cut 1 inch of the yolk, did a little fancy work, polished. I could not even tell it was cut. He charged me $20.00. I am doing a EFI conversion so I do not know how the rod situation will work out..

So he cut the yolk from your C4 and you did not need the new one? Whos kit did you use and were you happy with it?

Thanks!

Cutting the yolk does not shorten the distance between the rear and tranny tail. You'll need to have the drive shaft shortened. All cars are different so no single dimension can be given. You'll have to measure and advise your driveshaft shop of the dimension you want.

geostang351 is correct. If you use a C4 yoke, you have to cut it off because it is too long to fully insert into the AOD. That does nothing to reduce the distance between the transmission (which is longer than a C4) and the diff.

It is possible in many cases to get the original unshortened driveshaft to fit, but you end up with inadequate clearance between the yoke and the transmission.
