Hi, I'm just wondering if our 1st oem 18" would fit on the g's or m's. Since I have 2 sets of 18", 1st is 03-05, 2nd is 06+, and I'm getting a set of 20". So I'm thinking if I can keep a set for my winter set and sell a set to anyone who wants a set of 18" for their g's or m's. Please let me know of your thoughts. Thanks in advanced!!!
