Thinking of selling or trading my ALL REDONE Muncie 4-speed trans looking for price what they are worth-- straight shift pattern side panel 7 bolt-- drain plug Includes levers 3925660 3952648 3857584 19W51233 381020 P9E14A
3925660 case # indicates 1968 -1970 unit, I'll go out on a limb and say the double grove on a 10 spline input is a M20 wide ratio box. Good 2.52 1st gear ratio. That's a $1000 setup with the Hurst Super Shifter.
I just sold two Muncies without shifter, with the paperwork of the rebuild...$1,500 for a M22 Rockcrusher and $1,250 for a M20 wide ratio. Shifters are going for around $200 separately.
I just paid $300 for an M20. When I got it home I removed the side cover and the internals looked absolutely new. It didn't come with a shifter but for that price I didn't care.
It's a 1969 Muncie out of a SS Nova...had to be out of a SS 350 or 396 car. Anyway..I agree it's a $1000-$1250 piece with the shifter..
