RCR Gt40 Rocker Install?

Mine was done by RCR. They drilled and tapped holes and were screwed directly to the chassis. Probably four on each side - evenly spaced. Let me know if you want pics or have questions. - Alan
I mounted mine on the upper side of the chassis flange using nutplates rivetted to the rocker. I found that when balancing the overall width at the rocker edges & getting the upper rocker flange to sit flat the top of that flange was the only way. The net benefit was that the chassis is the low point and not fiberglass.
Thanks. I over thought it since my panel on underside has a 90° lip that clearly needs to be trimmed off to be flat against underfloor.
