Muncie M-20 4 speed transmission, 2-line input, 660 case, 1” pin, all numbers in the pics. 2.52 first gear, 1.88 second, 1.46 third and 1.00 fourth. You can confirm by the numbers if it fits your application. 10 spline input, 27 spline output. Case casting is 3925661 and correct tail is 3857584 - Side cover is correct with the casting number 3950306 with bolt style arms as shown. Will need a new bearing retainer, this one has big grooves from the throw-out bearing - Bench shifts fine in all gears. Everything looks decent inside, engagement teeth in good shape and constant mesh sides are good for their age as well. Case and tail are in good shape with no cracks or stripped threads, except the tail has a small 3/8" hole were someone ran a shifter mounting bracket bolt in too deep as shown. Price can be negotiated for an extra tail without a damage hole or bearing retainer. One cross member bolt also has an insert installed - Top boss of the case has some minor scratches as shown in the pics - Pics show all the numbers - VIN number is 19N686859 and date is P9P16A - Tin tag is still present and stamped 3950356 - Transmission appears to have been installed at the Norwood plant in a 1969 Chevy Camaro originally. Good core trans to restore in need of a full rebuild with new syncros - all original with good numbers as shown.
