M-21 Close ratio 4 speed transmission. This unit was restored to like new by Puyallup Transmission. At present it has 900 miles on it.
It operates like new with no issues. I replaced it with a Tremec 5 speed to help with the 4:11.1 rear end gear ratio. NO CRACKS OR WELDS and NO HELI-COILS.
I also have a new C-2 shifter linkage with arms and a new 10.5 center force clutch kit. The shifter kit and Clutch kit together are $500.00.
Call show contact info for more information.
