Welcome Phil,
Glad you found the site and joined in to the conversation. I have seen the yellow car several times it is a bad ass ride for sure. We have 2 roadster shop frames in the shop right now one for a 57 nomad, one for a 55 pickup. I can tell everyone first hand these frames are hands down the nicest frames out there for tri fives short of having something custom built maybe. I have seen the Chevelle frame and looked over pretty close it has several advantages over a stock frame. You can build up a stock chassis all you want but you still arent going to be able turn worth a dam with a 275 front or stick anything over a 10" wide tire under the rear without major surgery. Trust me I know I would be happy to take pics for anyone because I have a chevelle frame that I cut the hell out of and decided to stop and go with a aftermarket chassis. The one thing the RS frame offers that Art Morrison can not.........is the RS frame bolts in. Buy it bolt it in finsh body work and go on.
I hope you guys sell the **** out of them Phil
