Put the rear driveshaft back in, interior back together, didn't feel like waiting until tomorrow for a gasket to arrive, so bought a sheet of Felpro cork gasket material and made my own Dana 300 inspection cover gasket.
Traced the cover, used a 5/16 hollow punch that fit through the covers bolt holes to make the holes.
I still had the old gasket, still in one piece, so it was easy to trace out the inner cut line. I used sharp scissors to cut the outer line, X-Acto knife with new blade to cut the inner line.
My 5/16 holes were a bit too small, so used the 3/8 punch to open up the holes, give me some wiggle. The chamfer end on the punch will center up in the smaller hole. Worked well.
Ta Da.
Fits really well.
One hole was a hair off, easy enough to trim it out with the X-Acto knife.
That concludes my arts and crafts for today.
