I bought Permatex Ultra Black Gasket Maker so I could put the rear differential cover back on.

Per the instructions, I made a quarter inch continuous bead all around the cover.

I put the top and bottom bolts through the cover and used them to position the cover into place on the differential. Once these were in place I hand-tightened all the bolts down, utilizing a star pattern. I had to leave this sit for an hour before I torqued the bolts down to their 30 ft lb spec.

Here is a closeup of the Pontiac arrowhead stainless steel bolts.

I received two packages in the mail today. The first package was from Mark Puette.

It was the gullwing knight-head emblem pins I ordered.

The knight-head and the back of the pin is a heavy black nickle plating that has a dark mirror finish. These look awesome! Thanks for making these Mark!
