Hi Joe, can you measure that pulley opening across? It appears (from the photo) the factory washer will not fit that particular setup?

The OEM Flathead washer measures .312" (thick) x 1.560" (O.D.) x .660" (hole size).

The Pontiac washer measures .310" (thick) x 1.625" (O.D.) x .655" (hole size).

The OEM (8BA) Flathead bolt measures 1.625" (O/A length) x 1.150" (UHL threaded) x .875" hex nut (.470" thick).

The Pontiac bolt measures 2.000" (O/A length) x 1.600" (UHL threaded) x .937" hex nut (.400" thick).

Thanks, Gary in N.Y.

P.S. I know there's different opinions above on the torque for these size bolts but I definitely would want to at least be in the right neighborhood! For instance, if you back the torque way down your wheel lugnuts who do you blame when your wheels "fall-off"?? (More or less kidding here, maybe)
