I either want to rebuild the rear end, or i want to throw in a different one... but im more a fan of rebuild so i know whats in and what its been through, so on that note. i have an N/A LSD rear end, and i want to keep it that way, so, is there anybody in nor/cen CA who does it? or do i have to send my rear diff to somebody to get redone? Just kinda wondering... Thanks.
