Calling around to different wrecking yards in the Portland area makes one lose heart pretty fast. American classics has the only camaro/bird 5spd T5 I could find and they wanted $750 + $200 core charge YIKES

I called a guy just north of me (www.darkhorseperformance.com) who sells a GM version of the Tremec that is supposed to be a bolt in replacement of a Muncie. Right at $2k with the front shift position, output yoke.
ebay is looking better as far as prices go.
