I have a driveshaft which uses 1330 style u joints.do you know if anyone sells conversion joint so I could use that driveshaft with the original -52 rearend. Neapco 2-2091 seems to be for the 1310 style u joint.
Just about everyone sells them...........I got mine at O'Reilly's. Just bring the driveshaft info and the differential info and see the OLD guy behind the counter. Oops, Just noticed you were in Finland. Probably not going to be so easy. Over here, conversion ujoints are sold by all the chain stores. Not sure how to interpret your post, are you saying the Neapco 2-2091 fits your differential? EDIT.........by "bring the info", I meant the actual dimensions (in inches, not mm), because the store's computers do not go back as old as we need. You will need cap diameter, style of cap as determined by the retention system (clips or u bolts, groove/no groove, etc), and the leg length. In all likelyhood your 1330/**** joint will have it's own number.
You can do an online CHAT with these folks. http://www.drivetrainamerica.com/neapco-2-0291-2c-1310-conversion-u-joint/
Summit carries a lot of them. I also found this link that is very helpful. Everything you want to know about u-joints. Every bathroom should have a copy (laminated of course)... http://www.carquestprofessionals.com/catalogs/drivetrain/2013_UJ_CATALOG_CQ.PDF
