Breather mount pads are .250" billet aluminum where it mounts to the valve cover with two .312" fasteners on a 4.250" bolt spread. Breather pads use an O-ring to seal the mount plate to the valve cover to provide a leak proof seal. Breather hole in the pad is 2.125" x 1.50" in the rear tapering down to 1.250" in the front of the hole.
Racer can choose from standard breather mount pad or the Cebe titanium valve cover type mount pad from the drop down menu. Cebe mount pad has the small notch machined out of it for mounting bolt clearance.
Mounting pads are sold each so make sure to order two if needing a pair. Mount pads include O-ring, grade 8 bolts, AN washers and 5/16-24 jet nuts.
