I have these 1st gen wings down emblems in 3 sizes. 1.375, 1.75 & 2.5". They are a domed metallic polymer with a self adhesive back side. 1.375 fits inside the formula steering wheel horn cap. The 1.75 emblems fit over the PMD rally 2 plastic centers. The 2.5" will fit on the rear axle end , for a custom look if ur running stock rims. Quality is very good. They are $20 each shipped. $30 for a pair. Sets of 4 are $40. Thx nick
