Trans-Am info for the 1966 Barracuda

Our intent is to participate in the Historic Trans Am series that runs in the US. I am speaking with a few competitors who currently run this series. I currently run in the Monoposto 70 and BOSS series. The cars I currently run have their FIA papers and/or Passport (one car was actually accepted to run at the Monaco Historics F3 event).

What I am currently trying to ascertain is what is accepted vs what was allowed during the era vs what I would do for safety measures.
