Review on Securely Mount Your Ford Super Duty Truck Cap Topper with JQuad FCSD Mounting Clamp (4 Pack) by Charles Osguthorpe

I bought these for my 2006 F150 6.5ft body and ARE fiberglass topper. They fit perfectly. I had to replace the original ones. One of the things I did with the new clamps was coat the threads of the bolts with pad lube to make them easier to remove in the future. The originals appeared to be rusted/welded together and had to snap off at a screw to take it off. I originally ordered another brand that was supposed to fit my F150 and work with my ARE fiberglass lid, but the top mount clamp "bit" was too small and would not allow the top clamp through the ARE fiberglass base and trucks - Snap the body into place. side rail. The new ones worked great! Good product!
