I got a set from Rock Auto and the diameter of the bolt was larger than the hole on the diff. They were manufactured by MOOG, and named "Problem Solvers", The cam washers were not secured to the bolt like the stock ones, they just slid along the bolt that had a flat area from tip to bolt head so the cam washer would slide all the way down the bolt. Since they were made by MOOG I thought they'd be a perfect fit till I tried to install... they wouldn't slide thru the holes on the diff. Returned them and used the stock set I had. I guess the best bet would be to see if Dodge parts has them available. I do concur that they're available from LMC but wonder if they too would be from MOOG and be the same as with RockAuto?
