It appears some of my vague assumptions were close, thanks.
Ford38, thanks for the lead. I may or may not get that book. My car is a really mild mod version. Stance and interior changed, was born a 60 and is now powered by an 85. My interior is distressed vinyl with race belts for the seat and a cloth headliner. Paint is original and will stay that way. I have a build thread on our "sister" forum:

I just find some things worth looking into now and then, probably from 4 decades in the restoration game. Thanks again...
