It was serious inspiration for my own car.

Will, that car was the inspiration for my own car as well. He later did another 'cuda that was red and on Air Ride. That car was at Bill Reillys when I was purchasing my Alter-k-tion from there.
It was an inspiration in that it made me want to do the IRS from Heidts but the only thing I bought from them was a Wilwood kit, LOL. I settled for the Air Ride rear the Delaney's red 'cuda had.
The paint scheme, although what I envision my car replicating, wasn't the 'inspiration' moreover 'in-line with' my vision. Since I was a tike I thought the triple black AAR's were the sexiest beast on wheels.
That car the OP is inquiring about seems like they were copycating the Delaney car. I mean, same wheels? Delaneys car nailed the triple black look, this one is not far behind.
