Today I am converting a 69 Cutlass S 350 engine/350Tranny to a 455 engine and BOP TH400 tranny. in measuring both tranny's are the same length so the drive shaft length should not be an issue. The issue is the TH400 has a larger gear so that my current yoke on the drive shaft is to small. I called the local O'Railly's and they are lost. I need some info on what would be the best way of getting this resolved.
