I've got a small mountain of parts left over from my red 1990 miata.
Free stuff: Lots of it is in a gigantic trash pile that I'd give to GRM folks for free. Stuff like 1990 springs (stiffest of the NA springs, IIRC), seat belt tower panels, driveshaft, spare tire, fender liners, various heat shields/trim panels and a set of spacers for spec miata guys to convert to NB top hats (not the newer FCM ones), decent carpets, radio/hvac controls, A/C and P/S parts, etc. Not entirely sure what all is in there since the pile is pretty deep and has been building slowly.
For sale stuff: I've also got a set of tan leather seats from a '95 with one spot on the passenger side where the stitching pulled free along an inch or so at the front of the seat: $250. Hood: $100. Passenger door: $75. Trunk lid: $50. Top (a little ratty, glass window, good frame): $100. Headlight bucket (driver's, I think), center console (cupholder+power windows), instrument cluster shroud and dash also available.
I'm in Ann Arbor and am not shipping stuff because I have no boxes and am tired of messing around with the partout. Email me at grendel@gmail.com if you want to come pick at it. The trash pile is getting picked up by my junk guy sometime this week unless you give me a compelling reason to hold on to something!
