Now that I'm at the Ohio Key Sunshine Resort and Barth spa, I started on my projects.

Mag-Hytec makes nice cast aluminum differential covers. They have increased fluid capacity, a magnetic drain plug, and a dip stick (also magnetic) The extra capacity is due to larger internal volume and higher fluid level.

I decided to replace my cover while in the process of inspecting the gears and replacing the fluid.

Chevrolet used several axles on their chassis. I found this chart helpful:

The covers are available from the factory but I got one cheaper from an Amazon link.

My axle is a Dana 70 with 4.56 to 1 ratio (axle tag on 7'oclock bolt)

Gears look good, clean the case and mating surface

Install cover and fill. Love that dip stick!

Capacity is almost 2 qts greater and fluid flows in axle tubes as well as the center differential.
