The '66 is his brother in laws car he bought new with an L72 4spd.
These families were into high pref. cars in the era, the L72 was sold for a ZL1 69 camaro he bought new, owned for a few months then stolen and replaced with a 69 SS-RS Camaro L78 Baldwin auto-Motion modified and still owned by a family member today, It has not seen the light of day in 30+ years!
NO IT'S NOT FOR SALE and YES I'M ON IT!
Here is the original purchase order that Gordan saved and sent me this last week. It took three months from order to ownership and just about cancled the cars build. Glad he didn't!
