Nothing terribly different.
If you're being given a free hand stripping the thing, grab at least the following:
(Trail Spares)
Driveshafts (both)
Axleshafts (all - including front stub shafts.)
Front Axle disconnect actuator (to replace or modify)
(Goodies)
Trailer hitch (if there is one. Use it yourself or sell it.)
Anything you can think of that may be useful - glass and such, if you can store it. Also, lamp lenses and headlamp buckets are popular (I have several sets of taillamps for spares - I'm always whacking them - and I've got a couple sets of headlamp buckets and a spare grille.)
Bumpers (if they're different from yours, structurally.)
Interior parts (if they're better than yours.)
And, before you toss the thing entirely, can you yank out the control electronics - ECU and ICM - and set them aside for me? It's a personal project...
But, apart from that, there really aren't any changes to talk about, unless the 88 happens to have a D44 (last year for that option.) ChryCo only changed a few things in late 1988 1988/1989 break, then made some heavy swaps for 1991. Functionally, your 1987 and 1988 are identical.
