This was posted on the old forum and I just realized it needs to be on the new one too.
Fencl Tufo Chevrolet was a hi-po Chicago area dealer. Some paperwork from the dealership still survives. This is not a complete list of F-T cars, just the 1969 Camaro hi-po models (SS350 minimum) that someone saved paperwork on. If you have a car that's on this list, I can put you in contact with a person who can help document your car.
