I am looking for a seating system off of an old 626.

Seat Pan 16 3/4 wide
H frame mounting hardwear underneath for 16 3/4 seat pan
Straight seat rails
70 degree swing away hangers
Back 17 wide

Any of these will do but especially need the rails and hangers. I priced a new back, $525! Holy crap. Thats why I looking used first.
