96 chevy body on 95 yukon frame

I think the p/u frame kicks up in the rear sooner than it does on the yukon......however, you could probably make it work since the cab and bed are seperate pieces...it might look a little strange....but I think lifted trucks look strange to begin with.

I'm pretty sure the cab will, but not the bed. The yukon will be shorter than the ext cab truck

You'll have other issues with engine wiring harnesses and such too as the 96 will be obd2 vortec engine and the 95 will be obd1 with the tbi
