Not sure but I think Eric Humphrey crews for the Jones and Friend Funny bike. I believe that he ran an Econo type funny car in super pro or pro ET, I think it was white with blue flames and I am certain it had Jeckel and Hyde painted on the front valance. Possibly Monza or Mustang body cannot remember for sure.
Eric Humphrey was running the Jeckel and Hyde Pontiac at Avon Park in July 1991. I've just seen it in one of my dvds and it's listed in the programme running in Super ET Class
