Hey guys- I am new to the forum and have been reading up on your posts. I recently purchased 2 DD 4 53t's with intent of repowering my old jeeps. In my J10 I have swapped in 1 ton axles and a divorced NP205 which I with couple to an Allison 545 behind the 453t. I hope it works OK. In my '77 Cherokee I have GM HD 3/4 axles from a '73 C20 4x4. I would like to use a manual transmission but need some help with choosing one that will work. I got the GM axles from a neighbor who still has the rest of the '73 C20... could the transmission and T-case possibly bolt up? I have never worked on anything other than older Fords so I am not sure on what will swap. Any input would be greatly appreciated!

PS Would a 353 be better in the Cherokee?...bought the 453 cause it was CHEAP! Maybe I should swap???
