Well, maybe not quite vintage yet, but here is a Champ car circa the late '90's-00's. Couple more strenthening pieces, and I will make the first mold for the resin cast. The front wing will mount as a separate piece so it can be replaced. I may try to mold the rear wing sideplates in the main cast and then supply a separate upper wing insert? Don't know yet. What do you think?

She's a beauty, Gar. I like the replaceable front wing idea. Could you mount a small section of brass tubing in the nose and attach wing elements to it via press fit stubs? These would tend to come off in a shunt instead of breaking. It may not be a practical idea but I wanted to float it in case it has merit.

Keep up the great work.
