Removed the firewall for better access. Removed drilled mount points and deburred holes. The plans show the most forward holes on the bottom get a screw instead of a bolt, so used an oversize drill bit to countersink the holes in the mount. Bolted in the top mounts and the rear holes of the bottom. Reinstalled firewall and added screws on lower mounts. Torqued all the bolts to 25 inch/lbs.
