I have a set of 15x7 4 3/4 bolt pattern rims that a guy may want to buy. He is asking what the date code is. The only date I found is 1964 on the back of one of the spokes. 2 other spokes have patent #s and one has the cragar logo. It does not have the size or made in the usa on the inside like others I have seen. The warning sticker on the inside goes on to say that they may not be recommended for 65-66 full size pontiacs and oldsmobiles due to fender interferrance. Anybody know cragar rims inside and out?
