Hey guys I thought I asked this before but cant find it in any of my old posts! Im trying to get a decent rear and have realized I may soon be looking at some non Mopar cars to get it. So Im trying to get all the measurements I need. Thx guys :thumbup: Tryin' to get this info tonight so I can start researching it!
