[N2Cobras]

HELP! It's the first beautiful day since I got the car last winter, trying to get my SPF Cobra out for the first time and one of the snaps refuses to release on the tonneau. I taped old credit cards to protect the body and tried to pry off with slotted screwdrivers but it does not want to budge. It's a smaller headed snap by the driver's door. A regular thickness 5/16" open end wrench doesn't fit between the body and the cover, I figured I would just unscrew it, is this a good idea? I don't have any ignition wrenches that size or I would give it a try.

I tried to post pictures of the snap but the upload window wouldn't let me post either in .jpg or .pdf that were within the file size guidelines, maybe it's because I'm a newer member?
