Try Pelican like DD says using the phone. I just threw out the good one from the 70 I had. Guy who wanted it flaked out.
The other place that might have some good ones is PartsObsolete. Ask for Gary he has a ton of stuff in pretty good shape too.
Oh yeah, try HighPerformanceHouse, Rich Botempi.
Finally, go to
www.914Club.com and post there plus ask Brad. If anyone knows he will.
Also, Dave at TriadWestPreformance.com might have some. He is very slow to reply so be patient.
