How can you tell the OEM and Corksport springs apart?

[gambit20]

Bought somelightly used corksport springs off a guy. He had the oem springs close too when he wad giving me the springs. I just wanna make sure he didn't give me the wrong springs. Do the corksport springs have any lettering or anything on them?
