i've been struglling with this for a while and no one seems to have any clue. i am trying to find out if a type r lsd diff will fit into my 95 del sol. at first i thought well its b series so of course it will fit, but i started to research it anyway and now im not so sure. i looked at quaife's web site and compared part numbers and saw that the diffs are the same between ls, 99-00 si, 94-97 del sol, and 92-93 gsr. the newer gsr and type r are the same. some one told me that they think that maybe it is just the final drive gear that is different. if anyone can tell me or has any more ideas please tell me.
