In that day (I was there) helmet and seatbelt was all you needed. That car was great, it had a ‘roll bar’. We used VW gas tanks. I would like to know what those contraptions are over the frame in the trunk.
Adjustable spring hangers, looked again. Washer bottle could be VHT, push button and squirt on tires. Neat trick then. We had to put it down ourselves the track never did it. Get so sticky on the line your shoes would stick and foot would pull out.
