Does anybody know if a 1.76 gear set will fit into a 1.68 carrier? I don't know what brand the carrier is, so calling the manufacture isn't an option. I understand this is a kinda vague question. I'm hoping someone can say "yes, the carriers are all the same" This is a short dragster unit

Thanks for any help

Dave, to my knowledge, all Powerglide cases [OE and aftermarket] are the same. Thus, the case will accommodate any gearset. Also note, each gear set ratio is a specific set [planet, ring gear, and sun gear that goes on the clutch drum], and they are all a specific match. An excellent resource is the Powerglide manual by Carol Munroe.

Good luck finding a copy of the Powerglide manual by Carl Munroe.
