I looked at the car years ago. Dan Fodge had shop Sacramento area at the time. Was proud of billet lower control arm and the arms going back to the rear of frame to help control launch. The car was in kit car mag if my memory is right. He was one of the first to install electronic fuel injection, and at one time had relationship with Rex from engines by Rex, Sacramento. Last I heard he was around central Idaho ? When he would need funds I would buy interesting parts from him. I have a early t.w.m. setup for f.e. with fast wiring and ecu I got from him years ago if you could use for $3ooo.oo . I was there when he hit the wall at Sonoma with customers gt 40 replica. The car was really running hard before the accident. He worked on a lot of cobra and ford stuff and had talent. If you look real close at filter element you should be able to tell the source. I have replaced foam in Bennett car fuel cell, it was not hard. Foam came in bricks that you replace.
