Maybe this is not correct, but I extracted that from a classification form. There states that Division I and II, trailered and driven, reproduction parts are acceptable (?)
Reproduction parts are acceptable for restoration as long as they fit, look and function like the original OEM parts
In certain classes (as mentioned) and for that organization
Is there a guide were to look for the correct parts so one can replace the incorrect ones.?
No there is no guide - been discussed here and elsewhere many times. Too many parts, change differences between plants and time periods, too many years to cover, different body types, options and so on to compile at this late point and not have it obsolete as soon as it was completed. Besides what would it cost in time, effort and what would someone charge for such a resource in a era where most/many expect information to be free (IMHO due to the internet).
Not that it could not be done - believe we had the opportunity in the 80-90's to begin the process. Just have not run across the people that know the subjects that are willing to dedicate their lives to compiling such a resource. Most are all too busy running their business's, have other projects, websites and responsibilities plus age related issues.
As an attempt to fill this void, sites like this one were established and are helped on/supported by many to make for a "living, breathing" resource for the same end. One car at a time if need be
As you have seen here owners can search out prior, more recent threads related to the part in question or ask and post pictures. Or if you have an assembled car post or email pictures so that the larger, noticeable things can be found and corrected. Nothing will replace an in person look with multiple sets of eyes IMHO to find most of the items or practices.
I mean, what we have to look for in the car to be concours correct..? Points to take care of.
Everything (as long as it fits in the description for the class) is looked at so everything is "fair game" when your returning a car to how it looked the day the first owner took delivery
