1960-69 Rafman heavy duty rocker arm nuts in bulk, count 36 = 3 sets of 12 . Some of the bests on the market, in quantity for those who want to save, or got more than one Corvair! Note: you will get the style of rocker arm in the main photo. I would recommend to replace all 12 if you have to change several. Don't forget, after many years of wear & tear, they can come loose by themselves. So replace them all; for those on a budget, we also carry used push rods, used rocker arms, don't hesitate to give us a call at 918-413 1548, or e-mail [email protected], we will gladly help you out.
