I am also swapping in an AOD. In my case its in a 68 with a c4. From everything I have found, only the yoke needs to be changed as the C4 yoke is longer, but the driveshaft itself needs no modification. I have even heard of cutting the yoke, but I plan on getting a new one. I found a good article and will post a link as soon as I dig it up again. AOD's come in 2 tailshaft lengths. Most cars, including the fox bodies use the shorter tailshaft which is the same length as the c4, at least in the 67-68. There is a longer version for the crown vics, lincolns, and other full size cars. Mine came out of an 86 Thunderbird. The AOD has a wider pan and I've heard of problems with exhaust clearance, espically with long tube headers, so mods may be necessary there. There is a guy in here who has performed this swap on FMX equipped cars and has been very helpful. He said his headers worked too, but I believe is car was a 351C.dablack said:Royce,
Thanks for the info. The reason why I'm asking is that I'm planning on swapping to an AOD and know that the AOD is longer than my C4. So instead of having my shaft shortened (insert joke here), I thought it would be cool to go ahead and pick up an aluminum one for a mustang if it was short enough. I will start calling around and doing some research on how much length I will lose w/ the AOD and how long the mustang shafts are and compare.
