Here’s a pretty cool shot of Wayne Gapp working on the 1976 Ford Pinto. This image was posted by Doug Schmitt who is the current owner of the vehicle.
This car is pretty interesting because it was built in-house by Gapp & Roush. The chassis is essentially a clone of the 1973 Ford Pinto which was built by Wolverine.
It is my understanding that there were many small modifications made to the chassis design over the years they owned the 1973 Pinto and those changes were incorporated into this vehicle.
