With the help of Mike S from Iowa, I have acquired the 1956/57 Fibersport-Crosley. Mike bought the car off e-bay last year. He contacted me about selling the car and I said yes.
The car sure has the lines of the flat sided Fibersport but was bobbed on the front and rear at some point. Also there is a crease in the sides from the wheel opening to the bottom of the chassis near the doors. This looks like it may be from some de-lamination of the fiberglass layers. Compared to the Siam Fibersport body this one has a fiberglass floor, front and rear bulkheads; bolted to the Crosley frame.
The chassis appears to be Crosley Hot Shot with many holes drilled into the frame to lighten the frame. Engine is Crosley, transmission 3 speed Crosley and rear axle is Crosley. Front tire rims are 12″ Crosley and the rear tires are 14″, need to figure out what wheels are. The 14″ tires are needed to offset the high rear gear ratio of the Crosley diff.
