I bought some msp struts and i got to wonder how to tell the difference between my ES struts and the msp ones? im probably being paranoid, but there are spots on the msp struts still black, almost like they got painted blue and they left the bolts on. they do say tokico on them. should that assure me enough? its just i looked underneath at my stock struts and they look the same. i hope i didnt get taken for a ride here....
