current set up is a th350 with a 203, just purchased a 27 spline 205 with a th350 adaptor that im planning on mating real soon...have some questions.... im assuming the tail shaft length will work and no shortening will need to be done??? also will a sm465 205 crossmember work with a th350 205 setup....any info on this swap would be awesome, also if anyone can tell me any of the odd and ends ill need to buy to make it work
 
The 205 will bolt to the th350 in place of the 203 the transmission outputs are the same. You can reuse the same cross member and bushings-they are the same. The front drive shaft will need to be shortened and the rear drive shaft will need to be lengthened, assuming the 205 does not have a slip yoke on the back. If it does, you will need a different rear drive shaft
