Several were asked to look at that car when we were at the Delaware Valley Nova Show in AC, NJ. The verdict was that it appeared to be nice SS Nova with some alum heads, no proof whatsoever of it being an L89 car.
I thought the car was briefly owned by the OCC shop
The car has been at Legendary for awhile, but there is still no proof. Remember, LMC will restore your car to your spec's, so if you say it's an L89, L72, L71 - that's what you will get. They won't authenticate it, or do your research for you. They are not a specialty shop, they restore many types of cars, so if you want a Nova that can compete with an SCW or NNN restored car - well..... send it to them
Personaly, I don't think there are any '70 L89 Novas, possibly '68 or '69's, but no '70's.
