Saw this on another site, thought someone might be interested in the R-180 LSD's he has for sale...

The guy races a 510 so there's a good chance those are R160s.

I thought about that too John, hopefully he knows what he's talking about and they are 180's... With all the parts he has for sale, it sounds like he knows a little bit about his cars...
