Mystery GT40 Kit Car

I think this is a modified Fiberfab Avenger [edit: yes, it is], but I’m not 100% sure so any feedback is appreciated. Maybe I’m just tired, haha. Anyway, it’s up for sale in the Hesperia at an asking price of $3,500 — write jjor8cer17@verizon.net if you’re interested.

    I’m always tired..lol
    Yes, that is the Avenger, I’ll get the exact model number, This is the one I dig the best as the whole rear opens, seems to be the rarest one too,
    If you look you will see the it was made for the VW platform and the rear cockpit is sealed off from the engine so you can pull small things or little people back there, this example is extra cool with a corvair engine adapted to a VW swing axle tranny, seems this would make a great project and that full tilt rear screams to make it mid engine.

    You know now that you mention it those do look like depressions for jump seats . Those would be good for small bags and such or small kids. It would make a nice space for a sound system too.

    I believe Fiberfab did suggest that a person could sit back there, but it would have to be a small person.

    I contacted my friend Bud Short, the man I call the Avenger Valkyrie Guru to give me the run down on the linage of the Avenger,
    I believe this is worth saving by anyone even remotely interested in the Fiberfab cars.

    Here is what Bud sent me.

    “The first early model Avengers GT-12 were the two piece ones with the big opening tail section like the Early Valkyrie. Right after that came the early three piece avengers with the short tail section and the tilt nose section. Next was the GT-15 with the same exterior body as the GT-12 but with custom frame to accept Corvair suspension and different interior fiberglass panels, there were no 2 piece GT-15’s. Somewhere around 1970, they changed the body style to the bigger doors with Mustang hinges and one piece door glass,
    The early body had the smaller doors, had rocker panels under the doors. Used 1965-66 full size Ford door hinges and the front edge of the door went to the outside of the fender when the door was opened. Early model was intended to have the trimmed Mustang vent windows and the 1965-66 LTD 4 door side windows.
    The late model had the larger longer doors with the doors going all the way down to the lower body line, no rocker panels. Used Ford Mustang door hinges and the front edge of the door tucked inside the front fender when the door was opened. Late model was intended to use special Fiberfab one piece side glass but the early model glass arrangement can be made to fit the late doors with a little work.
    (I was off playing war when that change happened). Still 3 piece Avenger and 2 piece Valkyrie but the Valkyrie wheelbase was lengthened. The next step was the one piece Avenger and Valkyrie. Fiberfab offered the one piece body with all the stuff assembled such that the all the builder had to do was drop the Avenger body on a VW bellypan, hook up the wires and steering wheel and drive away. Engine access on the Avenger 1 piece was through a trap door in the tail. Engine access to the Valkyrie one piece was through the rear window hole, the glass Mustang fastback rear window was replaced with a fiberglass louver assembly so it could be hinged for engine access. The next version was the GT-X body style with a different shape on the tail, longer skinnier hood vent areas, and the front spoiler molded in.
    All Avengers and both Valkyrie models share the Corvair windshield.
    I think there were some overlaps in the body style availability where the adjacent styles were available at the same time. I personally prefer the three piece body style because it was the only style that had the nose section that opened up. I also prefer the early body over the late because they were build more rigid (even though the door latch assembly is more cramped in the early). I have had both early and late and the difference is really obvious when you have them both sitting together in the same shop.
