my tires are about 30" tall and gear is 3.73, I got the AOD trans mocked up in the car now. The trans is longer, so the mount is past cross member by about 1 1/2". The drive shaft is too long now. Typical street rod stuff. I'm pricing out the driveshaft work now. Heidts is about 35 miles from me, waiting to hear back from them $$.
