B&B Manufacturing out of MO has a mold for a 45" body which does not look very much different than the standard MKI... i got a body and chassis from them... waiting for delivery to start the build... it was up sized for a guy (he provided the money for the molds) who was over 6' and 200 lbs who didn't want to strugle getting in and out... not a problem for me at 5'8" but the price was right... if you want more info contact me... i don't believe he plans to make any more himself but i may be able to make it happen if there is enough interest... except for the hight and closing up the NASA ducts and door handle and hood pockets (which i told him he needed to put back in the molds) the rest of the deminsions are the same.
Hey adding 10% to a GT40 would make it a "GT44"!!! Remember the little shits that drove the original cars, Most of them were Jockey size. Like most of the F1/Grand Prix drivers were at the time. Then all of us "OFB's" (old fat basturds) wanna Gt40! I'am glad my sorry ass is only piled 5 ft 7inches tall!!!!! RHD Forever!
It's been done before
Dax made a "GT40" but added an inch or two
My build thread is here - includes some good shots to show the proportions are "not too bad"
