just a driver/cruiser I wouldn’t worry about the 3 disc direct clutch.
….and i always check input shaft end play prior to tear down. Can give you insight to wear or how far off it was in the first place.
.049 input shaft end-play. Figured while it was apart, I'd get it to 4 clutches. If I can find a 4 clutch drum, or machine the retaining plate......Still tossing those ideas around.
