Just picked up the parts to do the C4 to AOD swap with the exception of the driveshaft. I've read the AOD requires exactly a 1" shorter driveshaft, are new yolks required? Anyone have a shorter, correct length driveshaft for sale? What's the going rate to cut down a driveshaft, balance, etc? TIA

From what Ive read a C-4 driveshaft will fit the AOD but you may have to shorten the assembly . You can install everything and then measure the clearance on your tranny to driveshaft yoke .

typical $$ to shorten/rebalance a DS is ~80-125, IIRC. Your location may matter.

Thanks for the replies, fellas. I'd read the 1" comment from the Mustangandfords.com article but heard otherwise re. having to shorten the driveshaft.

You need the aod yoke and you should be ok. I didn't have to shorten my driveshaft changing from the c4 to aod and you probably wont have to either...

I agree with Ray. If you have the AOD yoke, you can use your existing drive shaft without mods. I have an AOD in my '66 and am using the same driveshaft I did when it had a C4 ... just attached the AOD yoke using standard '66 U-joints and stuck it in.

That's good to know, thanks for the info. Hopefully, I've got all the parts/pieces to do this. Have to check that list twice

When doing my T5 swap, my '65 driveshaft needed shortening 1". I took the driveshaft to a local light duty axle shop who did the following work:

1. Shaft was cut at rear yoke to reduce its length.
2. New yoke was installed at the rear of shaft and welded in place.
3. New slip yoke I provided was installed.
4. All new "u" joints were used.
5. Driveshaft was rebalanced.

Cost was $92 for the above. Note: I provided new slip yoke. Job was in by 8am and out by 2pm same day. Total labor on my job was 1 hour.
