do you want to keep a full time case or does it have a part time kit in it? You may need to find an adapter that will let you bolt it up to the 4l60, maybe advance adapters. I aint a hundred percent but I think they have the same tail bolts and pattern as a 700r4? if so then it's the same as a th350 and all you need is a th350 or 700r4 t-case adapter which came stock in these trucks so should be easy to find. I'm not completely sure of the tail though so might need to research more, if not then advance adapters should have what you need. I thinkmost 4x4 that had the 4l60 is a DS drop like the 88-98 trucks so it would be on the wrong side for your front axle. That may not be a problem if you wanted one of the newer like 241c t-cases but you'd need a new front axle like a ford one or something with a ds pumpkin/diff. That could lead into alot of things, like steering, brakes, etc, that would need modified or changed.

If the th350 or 700r4 adapter would work on your trans you could use a 208 t-case or even hunt down a 205, maybe find the 88-91 burb 241 that has a ps drop.
