I found a V6 MM/D50 at the salvage yard. It's a "cash 4 clucker" so the motor is shot, but it still has alot of good parts.
It still has the TACH cluster, too. I took the clutch pedal and rear fender flares. It was only missing drv. side mirror, bench seat, and wheels, otherwise everything else seems to be there. I'm not sure if I want to cut up the rear fender flares i got to fit my custom rocker panels yet. If the price is right, I may go back and grab the front fender flares and sell the complete set.
If anyone is interested in the TACH cluster or any other parts let me know and I can call them a get a quote. This yard is typically higher then some of the others, but its the only one that usually has a MM/D50 around here.
