Hi John, 1/2"(diameter) x 20(thread pitch) that was too easy...ask something harder! BTW most of the major suspension bolts are that size except the TABs(. Rob Grady P.J.Grady Inc. -----Original Message----- From:John Dore Subject: [DML] thread size of upper rear suspension bolt? Does anyone know what thread size is used where the rear upper link arm meets the chassis? The suspension bolt here goes through the suspension arm and into a threaded insert on the frame, and it is this thread size I need to know. Thanks!
