I remember reading that you would like to see proof ie: original window sticker, build sheet etc. or other that they offered the N66 wheels on the 70 Novas. I tried high and low but could not find any of the above then I realized that I had seen a several copies of the GM Canadian documented Novas and sure enough the RPO N66 was there on a couple. I remember you said you tried to order them on your 70 Nova new but the dealer said they were not offered, just like Vernes dealer telling him that he could not order Tuxedo Black on a Nova but you could. I feel that someone will turn up with a original Window sticker someday showing the N66 wheel but I never seen one either. I still believe that they were available as per the assembly manuals and brochures in 70 and seeing original cars back in the day. I think your dealer was wrong or mistaken. Alot of dealers did not know about COPO Camaros either but we all know now they were available. I always thought on 69-70 Chevelle SS that the N66 wheel was standard. Tom when I clicked on your attachment to see the Red Oxide primer all that popped up was that Beautiful Black Nova! Just my thoughts
