Is the addition of a RH OSRV mirror (not offered as an option in 1972) a modification? Also, the addition of P02 Wheel covers (Offered as an option) How about a removable hardtop? Another thing; years ago I took out the AM/FM stereo radio and put in one of those aftermarket radios with a tape player that required no dash cutting or modifications (I have the original radio and can reinstall it) The 10.5-inch clutch was replaced with an 11-inch clutch (which I believe was standard on only the '72 big blocks and then all '73's) I'm thinking about showing the car and I believe that in most cases, three changes take it out of "stock" and into "modified." Would appreciate some input. Thanks, Dan D.

Define showing. What type of shows are you going to enter it -
Re: What is considered a modification?
Dan,
Are you are planning to have your car judged by the NCRS? If so, I would suggest getting the Judging Reference Manual (applies to all years) and the Technical Information Manual and Judging guide (for your year). The mirror add on would generate a deduction, though I don't suspect very many points would be lost. The wheel covers would be judged and deducts would be made as appropriate for condition, etc. Assuming the configuration is typical of factory production, the judges wouldn't know they were added unless you disclosed it. You would probably be wise to reinstall the factory radio. The clutch isn't judged, but if the starter and bell housing were also changed, I think they would be.

Re: What is considered a modification?
Thanks for answering / I'm new to this so that's why it's taking me so long. I'm talking about strictly "small time" local stuff. I've had this car since 1985 and it was never intended to be a show car. I drive and enjoy it. The car is pretty nice though. Still has the original paint. I have had a new frame/ trailing arms/ "A" frames put in and last year had a new interior and top installed. Everything is stock though. My Grandson is showing some interest and I was thinking more of something to enjoy with himComment

Re: What is considered a modification?
Dan,
The rules used in NCRS Flight Judging are very specific and consistent. I'd suspect that the type of show you're talking about would be less so. Best ask them.Comment

Re: What is considered a modification?
NCRS judges only deduct for non-factory items which they can see. I have a right hand mirror on my 1972 because it is a driver, and I refuse to drive on multi-lane streets without it. It gets a minor deduction for the two holes in the door. The mirror itself is not addressed.
As for the other items you mention, deduction would depend on how much deviation there is from the original. Order a copy of the Judging Reference Guide and the 1970-72 Technical Manual from the NCRS office. You can download sample judging sheets at https://www.ncrs.org/membership/scoresheets.html to look at point assignments.
Congratulations on trying to bring another generation into the hobby.Comment

Re: What is considered a modification?
Don't ask anyone - it will only start needless discussions among persons with little or no knowledge of the rules and how they came to be in effect. Simply enter the "stock" class and be done with it as the alterations you have mentioned should not be enough to put you in a "modified" class which is generally reserved for severely customized cars, ones with engine swaps, altered suspensions, etc. Go to some shows and enjoy the cars. You'll soon see that the line between "stock" and "modified" is an elusive boundary, but as was said about pornography, "you'll know it when you see it."Comment
