This is not mine (although one of mine is up there) but it appears to be a nice '70 Monte.
I don't think it is actually an SS but it is a pretty car. Some of the issues I see are...
1) no air ride compressor
2) 'SS' steering wheel logo??
3) Rear lower control arms are not boxed.
4) Exhaust is wrong
A friend actually called the guy on the car and there is no build sheet for the car (VIN not given so it may just be a Flint car) and the motor is not original.
