Anyone have the part # on the outside of the box for the front pad of a GT350, it starts with GPM and then 4 numbers? Just received pads from OPMustang and put on the front but theres more pad than rotor. Looking at my old box which are just the street pad it says GPM1853-GS1, this box says GPM1835-R18. I am thinking it should say GPM1853-R18, but wanted to verify if someone had a box handy.
