Was my understanding, at least in the past, that the Owner/Driver were responsible for properly classifying the body. Engine, safety etc taken care of by tech. If someone objected, they had the option to protest. Perhaps recently the inspectors require some proof of proper classification.
In 1986 and 1987 a Ford EXP ran in gas and fuel in GC, ALT, CC and GT classes and set records, some of which still stand. This was done by changing the number/class designation on the car,(and for sure without meeting all the requirements for all these classes) a process which is clearly prohibited in the rule book. Not to mention that a car cannot run production and GT as noted in the above posts.
I protested (though not at the meets- which is required I now know). I never had the courtesy of a response. Think that the owner being on the board had anything to do with that?
I am sure such a problem would not occur today ( at least I hope not)
Sorry for the rant. Has bothered me for years.
