help verify a yenko nova .?

[SuperCars]

It's a 69 Nova. I've already been contacted by the son of the Widow. the deceased owner was his step dad. The son lives in Alaska and he gave me info from his Mom the best he could; but she was only able to do so much. The VIN is a quite high late number and not close within the group of other known Yenko VIN's. Also it has front fender side marker light emblems with "307". Either the car was originally a "307" or someone would've had to change those. Didn't get as far as asking whether it had a 10 bolt or 12 bolt, motor numbers etc, as I assume his Mom to be an elderly lady that wouldn't appreciate crawling under the car. No stripes graphics, etc. The only identifable Yenko item was a Yenko badge on it.
