- 3/16-inch thick wall construction to add strength to differential housing
- 3/8-inch thick gasket flange will not bend when bolts are tightened

I should have mine tomorrow.
I ordered the cast sand so that way I can paint it burnt copper to match my valve cover. I will keep the fins the sand color and the rest will be colored which should look like their powder coated version. Can't wait!
I'll post pictures once I get it.
