Parts that are unique to a 96 mark?

I have a 96 that really needs nothing (well, wheels would be nice, and maybe a bunch of mods, tuner, etc...) but I have read on here that there are specific things about a 96-I know it's OBDII and other Gen 1's are not so the ecm is probably unique, but what other components are specific to 96's, ie the VCRM, or any other items?
I ask because as it gets older, I'd like to stockpile now items that might be impossible to find down the road. Thanks

The IMRC valves are 96' only as I am throwing a code for them.

The wiring harness and a lot of electronic related things are 96 specific.
