it cost me $120 to get mine bored out, but the guy told me it took a little longer since they were chrome, if they are the regular machined look it may cost you a little less, im not sure of the exact size they went up to but not much you should be able to call your local mazda dealership and ask them what size hub is on your truck, then take it to the machine shop and have them bore them out, as it was said you can just grind of the tabs but then you are basing your safety on the wheels bieng centered on the lug nuts, ( which you have to get larger bulge style gm lugs to make the wheels work) where if you bore the hubs the wheels are whats called " hub centric " centered and balanced ont he hub properly, so the choice is yours
