Now that I have the NOS wheel in hand - no pun intended- , I can see what Charles was saying. There is indeed a different feel between the two, and the NOS wheel feels a slight heavier. I will say that the repro "looks" much better than the NOS, with the Ford wheel having mold imperfections and a dull/scratched appearance in some places. I was able to use a foam pad and Plastix to polish it up a bit, more to my liking.
The repro wheel I had lasted 6 years before it finally gave way to two cracks at the mold injection points. The NOS wheel I have on my 67' has been there for 20 years and still in the great shape it was since I installed it. Luck I guess, since I know direct sun and changes in temp play a big role with wheels cracking.
Here are some pics I took to capture some of the differences between the two. Hopefully this will help out those questioning a true NOS wheel.
Repro wheel vs NOS wheel
Mold points are rectangle in the repro wheel rim - NOS is round
TS detent underneath is painted black on repro - NOS painted Orange
Center hub plate on repro is attached with Allen head screws - NOS wheel has spot welded center
Injection points on 3 spokes, repro is larger, oval - NOS, which has a slightly smaller oval, and a mold ring around the injection point
Wheel grips look very much the same with a similar measurement for grip
Also noted is the hardware (screws) on the NOS seems to have a yellowish coating? while the repro is likely just shiny cad plated.
Plastic pieces for the horn contacts are a darker white on the NOS, but then again could be from age. My NOS wheel I picked up is from 1990.
