Hi
No idea on the air compressor. Your best bet is to find someone parting out their car here on the board, ebay, or checking at
www.mr2trader.com.
As far as seats, i can get them, but i can't ship them, they are way too big and unfortunately, i am limited on the size and weight of items i can ship. If you are wanting new seats, you might try a dealership, check with lithia here on the board and ask them.

Getting them recovered, it would probably be cheaper to get new ones than to have yours recovered, i priced it about 2 years ago, and they wanted something like $1200 for both seats in real leather. I'm sure you can buy them new from toyota for cheaper.
