Driveshaft questions on 93 4x4 blazer/tahoe

Planning on doing a swap on my friends 93 blazer/tahoe,, 2 door 4x4... it has the orginal stock 350 and trans... we have a engine ,, 5.3 and trans 4l60E with manual transfer case from a 2000 model truck,, with dirty dingo mounts.... should this drop in without having to make any mods to the driveshafts??

Also will the 2000 model manual shift transfer case require mods to work with his stock t-case shifter??

If its the one inch set back mounts, then the transmission will remain in the stick location. If it isn't the 1" set back mounts then the trans cross member will have to be moved, front shaft shortened and rear lengthened.

thanks,,, we should be in good shape!
