Extang Cargo Cleats????
 

Has anyone used these: Extang Cargo Cleats? Further more, has anyone used these WITH an Extang tonnuea cover?

I have an Extang Tri-fecta and I don't want to buy these if they wont fit with the cover. I know the website says it's cool - but I thought I'd ask for some first hand help here.

Thanks All
