      It keeps the bolt from coming out of the bracket.

          Sorry if I was not clear. I am not referencing the knob thingy (aka bracket nut) that threads ONTO the bolt and yes THAT part keeps the bolt from coming out of the bracket. I am referencing the roll pin that goes INTO the slot at the very end of the bolt. Only thing I can think of it keeps the knobby thing from accidentally spinning off the bolt...and I think I just answered my own inquiry?? Or no?

              I think you did! Just keeps you from running the bolt out too far. Chip.

                  I just used a roll pin from the hardware store to replace that pin on the end. No need to buy it from anywhere special.

                      Agree with Mark. It prevents the bolt from coming completely out. It's a safety item. If that bolt comes all the way out with your hand under the tub that contains a tire it will result is several stitches when it falls on you. Don't ask me how I know, something stupid I did when I was 18.

                      Also, the early pins were not rolled, they were a solid steel pin. I can not recall when the changed to a rolled pin.

                          The pin was always solid steel from 1963 to 1982. GM #9420488. Never available in SERVICE.

                          A roll pin as mentioned by Patrick will serve equally well and, likely, better.
