I have a M-20 Muncie that was pulled out of a running/driving 69 Chevelle SS. Transmission worked fine and is in nice condition. All the internals of the trans looked fine including but not limited to the gears and syncronizers, shift forks, detents, etc. While I had it apart I put in a new rear bearing retaining gasket, new extention bushing, new lip seals for the shifting shafts and a new rear oil seal for the pinion. This trans. has a case # 392560 for 1968-70 and has the correct gearing ratios(2.52, 1.88, 1.46, 1.00) - $750 + shipping but would rather deliver to Bowling Green with no delivery costs. Larger pics can be sent to an email address.
