I purchased a couple lsd from a guy on pirate 4x4. they where suppose to be 8" 1 v6 and 1 4cyl. The first 1 to arrive is a 12 bolt ring gear. Is this like for a cruiser 8 7/8 ? The only number is 01110263. claims its 8" yet and its suppose to be TORSEN brand. i searched and they don't list any #'s like that. Any help out there on it would be great .THANKS JIM
