zentech Posted December 29, 2013 Share Posted December 29, 2013 I believe i have two of those K-case r-180 diffs. Can't remember ratios off hand. I'll check. What i have is an R-200 clutch LSD though. Quote Link to comment Share on other sites More sharing options...
malibud Posted December 29, 2013 Share Posted December 29, 2013 I am curious if you have a 4:11 why do want a 3.9 . I have a 3.9 in my 240 with closed ratio 5 speed love it but was planning on going to the scrap yard this week to get a 4:11 up grade was wondering if you thought it was too low. Going to keep the 3.9 as a spare sorry . shipping is about 80$ one way Quote Link to comment Share on other sites More sharing options...
