ok i know on the lsd diffs there is a viscous sticker on the side orange in color but there is way too much crap in the way to see so can i tell any other way? like bolt pattern or do i just have to stop being lazy and take suspension off to see? when i launch and drift i get about the same tred marks down but that dosent tell me for sure..... thanks for the help and this might be a stupid question im not sure
