Same style u joint my 31 model A has. Put the car all together took it for a spin the trany just howled in 2nd gear, like loud. Pulled diff, took trany all apart went to bearing supply with used bearings figuring ya right their going to have these ha. 78 bucks later I had all the bearings for tranny. Put tranny back in car still howled. Did some research found out there are two 3 thousand slims that go behind the top two blots in the flywheel housing against the engine block put them in tranny shut up never made another peep. Blew my head
