I have a '56 272. Some of my rocker bolts will loosen up quicker than they should. One side has the over sized ones (7/16th) and the other side has the stock ones (1/2"). Does anyone know where one could get the ones like used to be around that had the screw and then the nut that tightened around it? The '57 I used to have had that and it was a lot better than these one piece things. Thanks ..
