groundhog47 347 #1 Posted July 1, 2017 (edited) Would any body have a copy of Service Bulletin number 252, manuals/transmission doesn't have and my dealer manuals stop around 156, couldn't find them in 74-80 dealer manuals. Service Manual says: See Service Bulletin number 252 for conversion of limited slip differential to 8-pinion differential. I figure it would reverse also (10 to 8) and have already seen post on procedure Edited July 1, 2017 by groundhog47 Share this post Link to post Share on other sites
