Stacey David hisself probably signed off on this kit. Revell presented him with the box art build and he must have said "Looks great!"
We have to remember that, for the car guys that don't build model cars, model cars are just office/book shelf decoration or "kid stuff."
The lack of an under-floor master cylinder, or a correct I-beam even, isn't a deal breaker when you look at this as an "arm's-length replica."
Or, maybe Stacey did say something, but it was too late to retool. Either way, he had to sign off on it - his name is on it.
