That's a very interesting car...not like any Fiberfab car I've ever seen.they never came with doors like that. From the windshield back, it's much like the kellison..almost identical from pics that I have...but the front clip is like an avenger ..except for no turn signal recesses. I think it...

I bought an adapter,pressure plate/release bearing/clutch from them over twenty years ago for my 914/Rover 3.5l V8 and it's been flawless...I remember the clutch cost me US$12.00 back then lol!! I also bought a gear drive starter for that...
