There is a car for sale on BaT currently , with some document issues.
Currently labeled as a GTO.
Does not have a 2 in Box 38 of BHC
Boxes 74 75 76 77 are goofy also.
A google of VIN reveals prior sales as a LeMans.
Red flags everywhere.
I think boxes 75 and 76 have definitely been "adjusted" (YS) - incorrectly.
Cannot make heads or tails from boxes 74 and 77
Not well versed on LeMans or 3spd cars , or 6 cylinder cars.
But think Box 74 should be a 3 (2 if Auto)
Box 77 either S or X (J if Auto)
And could this have been a 6 cylinder engine since 326 2 bbl is not highlighted ?
