this is in the 360/904 stock car no problems in that area but people have reported issues there (lug engagement) & if I can head off a potential issue with a simple fix (like doing this) then I am up for it. I was over there today getting the eng ready to fire & FYI the TC has 3/8" fore/aft play and the nut(s) I used in the pic that I was considering were half that (3/16).
