Inferno Red 74 Duster!

Feeling pretty good about my progress. I got the fuel tank and diff out of the white car and am working on getting them ready to install in the red car.

Fuel tank is in great shape. What does everyone use to paint/preserve their fuel tanks? The whole bottom already has a healthy coat of undercoat.

Not sure what to do regarding the diff though. I have an A-body 8 1/4 with a 2.45 open diff from my red car and an F-body 8 1/4 with a 3.21SG from my white car. I'd really like to have the 3.21 SG in the A-body housing because I'd gain some tire clearance with the rims I currently have. They are 15x7.5 Aluminium slots with 3.75" bs and 245-60-15 Cooper Cobras. I'm thinking with the A-body housing I'd fit 275-60-15s on there which is the tire I want.

The 8 1/4 will be good for the short term as I have a mild 360, and lots planned before an engine upgrade.
