Thanks Ken for the link to the FIA Historical info. I had searched the site with no luck. It seams the words I used in my searches never worked with their search engine, but having the link to one page allowed me to figure out how to get to the rest.
So much for being clueless.
I have not read everything in detail from Historical Appendix J which seems to be the complete rules from 1961, 1966, 1969, 1970 etc., but skimming it does appear that the weights DID NOT FOLLOW homologation weights but engine size. The rule for the weight also was "As the car would cross the finish line" so I think this would even include the driver. Other rules of note allowed for the changing of brakes as long as the friction area stayed the same.
The FIA Group 2 rules seem to parallel SVRA's rules almost perfectly.
Time will tell how VSCDA responds.
