Premium reproduction rubber seal with the proper thickness of the 1967-68 seal as found on Mercury Cougar and Ford Mustang except these are not molded to the extension contours. Sold in a 52 inch length. Starting in 1969 this channel seal was manufactured slightly smaller which tightened up the gap on the fender and quarter extension seals. This seal maintains the slightly larger gaps.
Sold as a pair, two pairs needed per car.
*NOTE* Do not over tighten the studs that mount the extensions. They are made from a soft metal and will dimple easily in the area where the studs meet the extension. "Snug" the nuts gently.
