Shame you're not closer to Pgh...I have a spare set of Sachs struts, stock springs, shocks, rear arms with drive shafts, rims...straight front arms (bad balljoints though) and other assorted M20 stuff like oil coolers, alternators, starters, and a Getrag 260 with clutch swap kit.
The only M42 stuff I have is little stuff - a spare DME, throttle body, assorted ignition coils. I'd be thrilled to cut it loose for a fair offer as it would help me clean up the garage!
