Ok, yes big deal...
The 99' yoke has a larger ID or "more splines" than the 92 so i'm back to square 1. I dont know if the 92 tailshaft will work out since it has 2 sensors and the 99 has 1. If all else fails I could just pick up a used complete 99 d-shaft and it will fit.
I was thinking that would probably be the easiest way. Id do that. The people you got the motor from still have the drive shaft?
