what is concourse correct?

The lack of reponses is probably due to two things: It's probably safe to say that the majority of cars people here on stangnet have are either A) highly modified or B) supremely f'd up do to time and the elements. In the case of the former they are looking at performance upgrades, and in the latter they are trying to make the car driveable again. I'm definitely not saying it is out of the realm to talk about concourse stuff here, I'm just saying it doesn't seem to have a big focus and following.

I would suggest you try and make some car shows. I see a lot of original type restos at shows lately, and even some low mileage all original cars. Either way that would give you an up close view of how they are supposed to look.

edit: also, depending on how far out of concourse it is, I would suggest the shop manual as it has a lot of diagrams to different systems (i.e. the emissions) that show what is supposed to be there.

concours has lost popularity over the last 10 years thats why

the concours competetion is so tough that the judges have gotten to the point that they check the tires for proper "timing" ( valve stem pointed at the same spot on each tire) this is not being anal, it is because there are so many 100 point cars at a mca grand national show, they need points to whittle down the competition. i guess my point is, if you want a 100 point car for resale, or your own satisfaction, go for it, but if you want to compete to mca standards, either build for modified class (my choice) of be prepaired for some STIFF competition.

"Correct" concours parts, paint marks and the color of the underneath primer all vary from plant to plant (San Jose, Dearborn, New Jersey). There is not any single one "correct" way to do any specific car.

On top of that at any given show the person judging your car may have his own notion of what "correct" is. So be prepared for some inconsistency.
