I swapped out my 225 slant 6 engine out of a 1974 plymouth duster and dropped in a .30 over 318. I bought a 904 transmission and had it rebuilt, and after i bolted the transmission up, my driveshaft seems to be about 2 inches too long. I crammed it up there, but there is no play and it just doesn't seem right. I am not quite sure what to do. Anybody have any ideas on what is wrong? Hopefully I can get some answers. Might just have to take it down to the machine shop and have it shortened and balanced? Thanks for your time guys.

Are you sure it is a 904 and not a 727 ?? DO NOT try and drive it that way

That's happens a lot with engine swaps; either too long or too short. You're going to have to take it to a shop that does drive shafts and have it cut to size (or have a new one made, they should use you're old U-joints).

Unless the shop will remove the drive shaft themselves, they will ask for very specific measurements.
