I researched this for a while when doing my conversion. The input shafts are definately different. Also the 96+up GM bolt pattern are the same as the Dodge, get one from 95 and eariler and it will not bolt up to the dodge bell housing. Tail housing are different as well for the different transfercase options.
Since yours is a first gen and has a drivers side drop, the 2nd gen tail housing wont do you much good unless you run a advanced adapters to your current 205 transfercase , or run a divorced case (thats what I did) you could run the GM transferscase as well.
But to sum it up, make sure what year the transmission came out of.....if its before 95 dont buy it because it wont bolt up. Google the transition year to be sure, cant remember 100% if it was 95 or 96 that they changed the cases to be the same as the dodge.
