I havent dug through papers yet for the VA white Formula but had CRAIGSLIST search engine up today looking for something else and put in 1970 Formula. You can search the entire CL listings.
Here are a few older (by a two or three weeks) for sale:

Also a interesting site with members cars I have never seen before. Not sure if they have options to contact the members, but might be worth a try.
