carry the pad with you. it will be the easiest way to get the correct ones, and will help you figure out what caliper you have on there. it was a common thing for me to see mx-6 people come in and say their brake pad was too small when the previous owner used mazda 6 calipers as an upgrade and never even knew. same thing with savana vans, and k1500 suburbans with swapping of calipers.
