LT1 Swap into Cherokee

i have a 90 jeep cherokee. i plan to put an lt1 in it.

i have already bought a 94 NP241 out of a Silverodo, 97 4L60E out of a S10 Blazer.

my question is will the np241 mount up to the 4l60e even though it used to have a np233. i have the mount from the transfer case that went to the 4l60e silverodo it came off of. but i dont know if the shaft off the transfer case is the right length to fit the 241.

if any of you guys know lengths of the out put shaft on 4l60e's from model to model that chevy put them in it would really help me out.

thank you
