OK. I thought I seen the answer to this somewhere but I cannot find it. I did the 5.0 w/AOD conversion on my 64.5 convertible (Stang). I never got the original drive shaft when I got the STang so now that I have the motor and tranny in (and almost finished wiring) AND I have the rear end rebuilt ( standard 8" with 3.55 gears), I am trying to figure out what to do about a driveshaft. I did get a driveshaft from a donor 89 GT when I bought the motor and tranny from a 90 GT, but it is to short ( by about 5 inches). This particular driveshaft was matched up to a T5 orginally but I believe the Yoke will fit fine with my AOD. I can get my hands on a driveshaft out of a 70 Mustang fastback that is rusting away in a salvage yard - it is 54" from center Ujoint to center Ujoint. I thought I could take the two driveshafts to a shop and see if they could make one that would work for me. What do you all think? Will that work? I cannot find a 65/66 driveshaft any where nearby or I would get that and mate it with the T5 yoke. Any ideas about how much it would cost to have a shop do this? THanks in advance for the help.
