Hi guys, ive been looking to replace the rocker panels on my 57 bel air 4 door hardtop. I was just wondering if anyones ever used the "slip on" rocker panels? If so how was it installing them, and would you recommend them? The only spots that are rotted on mine are the front and back corners on the outside of the panel. The door jamb sides are fine. Any pics would be a help also. Thanks Guys!
