I've seen it done. I looked at an old Suburban for sale that had the engine replaced with a 96 5.7. The owner selling it owned an auto repair shop. I can't remember name of his shop though.... Sorry.
Maybe a few parts. Most parts will not fit.
Yes
NO it will not. You MUST put a 1996 4L60E trans. back in the tahoe. No other year will interchange. The belhousing are different.
Put it on a diet?
Yes. I have a 2004 Suburban with barn doors and I put these LED tail lights on them.Just do a Google search for Anzo 311003
