I am building a 68 cpe for my 16 yr old daughter. She decided to change the 3 spd manual trans for an auto. I have access to an AOD trans from an '89 E150 van. The trans bolts up to the motor just fine, but the crossmember will not fit because the trans pan is longer and wider than the C4. Does anybody make an aftermarket crossmember or do I have to fabricate one myself? Also, it appears that the driveshaft will have to be shortened about 1.5 inches which I know shouldn't be a big problem. I sure would appreciate any help.
