This winter's project is factory air retrofit into my 280SL (Euro) "economy"

model (6 cyl., manual trans., roll-up windows, cloth seats, no cruise control). I need a complete (mostly) 380SL for parts. 1982 through 1985 only, wreck, beater, or abandoned project. Can also be a Euro 280SL or SLC (same R107 body) with factory AC. Should be in Mid-Atlantic region, doesn't have to run, major rust OK, color doesn't matter (although blue interior would helpful). Has anyone out there done this? Understand its a lot of intellegent grunt work, but it would take my 99% car over 100%. Please see wanted listings in cars and also parts forums. Any leads appreciated. Thanks!
