As far as a test I do not know where you would get a good base from. I was a member of MCA in the early 80's. I took my 73 Mach 1 to the MCA nationals in Atlanta and entered it in unrestored original. They did not give the judging sheet to me there they mailed. They had a list of a bunch of items that would have to change to make my car do any better. I took third and never cleaned the undercarriage. I ordered it the only owner and it had 12,000 miles on it. The list of items incorrect included fasteners that had never been out of the car. The right front fender had been painted due to a friend of mine scraping a mail box door on it while I was on a trip out west. He had it painted before I got back and it did not match too good. Everything else was and is factory.
The judges at MCA wrote the rules to make their cars be correct it did not matter if they were or not.
MCA has approved vendors you use like AMK for fasteners to do a "Concourse Restoration". I got one of the Master Bolt Kits for 71-73 for a car I am currently working on. Every bolt on the car and I do not think a single one of them matches the originals. They all come in nice little bags marked exactly where they go. The maker marks are wrong the lengths are wrong the heads are wrong but they are considered by MCA to be correct. I personally know that one of the head judges changed the mileage on one of his 73 Mach 1 and changed body panels but he says it is a rare low mileage car with "Special panels". His car is correct by MCA and I know it was changed the previous owner was a friend of mine and he changed them.
It is like the old game we use to play in class. The teacher would tell a story verbally reading from a paper to the first student and then each student had to verbally tell the next from memory until you got all the way around the class. Then the last person would tell the story while the class looked at a printed copy of the first story the teacher told. After it went through 20 people there was noting the same. Numbers changed, dates, what happened it is hilarious.
That is how our cars are the owner tells you that everything is original nothing changed just like the guy before him told him.
Now I will jump off this topic. I am in a motel travel away from home got bit by the car buying bug again. I will go tomorrow to look at one of the off brands to buy and flip. It is a 1970 Chevelle SS 454 all original never restored, 4 speed, rock crusher, 12 bolt posi, cowl induction hood with flapper, buckets, console, lol. This is another one of those cars that is counterfeited over and over due to the lack of GM documentation. This one has not been painted and not rusty or wrecked. He bought in the 70's and put in a building and it sat there. If he does not have the original window sticker you can believe only what you can prove. It might be a find and might be nothing. He cannot even tell me if it is LS5 or LS6 and that is huge. One is a truck and bus motor and the other is a pure race engine. So if the vin and block numbers match I will probably buy but if not it is just like the light blue Mach 1 one mans dream but if it isn't real and right it is just a shiny parts car.
Everything might be there but without proof it is just a parts car.
