ST-10 4 speed ?

When in gear under a load the cluster would push back 1st,2cd,3rd gears. When these gears have all the end play removed then they would want to push cluster forward and neutralize cluster ( lack of a better term). 1st gear on Muncie's would be driven back with their excessive play and have less tooth contact and break the gear, plus other factors in breaking 1st gear. We would shim cluster all the way back in case and then put a shim behind 1st gear to keep it forward and tight as much as possible yet let oil lube inside of 1st to prevent seizing on main shaft. Seized 1 up once and had to drive over 20 miles home in 1st with 4.10 gears. Made my date get home late and her dad was not happy.
