Yup, Mark, that's the screw. Oddly, top one will catch but bottom one wouldn't when I added the mud flaps....suspect hand-made car explains that. Just curious if the JDMs with flaps use the same 25mm bolts or longer
Anybody across the pond(s) know?

Thanks Tom, I'll try Lowe's...we're going that way today. My HomeDepot seems to have zip for car screws/bolts etc...
