smokeybear Posted October 4, 2009 Share Posted October 4, 2009 If it is a 78 standard car it should have an r200. If it is an auto 78 then it might have an r180. But remember that sometimes people put different rear ends in them because the go out, get old, etc etc. Quote Link to comment Share on other sites More sharing options...
UPSMT280Z Posted October 4, 2009 Author Share Posted October 4, 2009 Im pretty sure its the orig rear end. Im also pretty sure that its a limited slip. I have the rear up up in the air put it in 1st and the left tire spins but the right doesnt, i them press in the clutch and then hold onto the left rear and slowly let the clutch out and the right wheel spins but i can kinda feel it wanting to spin the left. When i let go of the left it spins then right comes to a stop is this limited slip or and open diff. Can i get a posi for it? HLS30-454791 what does this tell me or where can i find out what this will tell me? Quote Link to comment Share on other sites More sharing options...
Two80z4me Posted October 5, 2009 Share Posted October 5, 2009 mine is an R200, when im doing a burnout, both spin, but then when I let the brake off and start going, it all goes to the right side and lays down one line, its a tempermental Limited slip, when im sliding both will light up, but when im just doing a burnout or getting on it to hard only one side spins while its moving. but both will spin in place, I think mine is just messed up.

hoov100 Posted October 5, 2009 Share Posted October 5, 2009 your best bet, is to pull the cover and see what it is. Quote Link to comment Share on other sites More sharing options...
