HM-mm, ck80, if you do decide to snatch your big block '96 and go retro to a square body, why not take those heated seats with you? The install and wiring can't be all that miserable or complicated. Either that or design a cow catcher but use cheap soft bolts to mount it so when you scoop the deer, the bolts break and the whole thing drops away so your front fascia doesn't get shredded.

Worse than a 96 for swap purposes, it's an 02 so gmt800 heading into either an 87 v series or 79 k series.
Seats are wider, it'd be a PITA to adapt the power seat track/heated seat onto a floor with the raised hump and smaller footprint. I believe the seat assembly is a good bit wider, certainly has a narrower console, and, the length of console wouldn't swap. A square suburban puts the t-case lever dead center on the floor hump, meaning the 800 console wouldn't fit so you'd have no console anymore between seats, meaning a bracket delete and custom carpet job.
I'm sure I could reupholster a different set of seats and add heaters, but, the memory seats with lumbar and heat are nice on the longer trips.
