Purchased a really cool Harrison overflow tank for my ride that was used in an original 289FIA cobra. This tank is sweet! I spent about 3 hours wet sanding it with 400 grit sandpaper and followed that by 3 grits of polish for 3 hours, and followed that with a few minutes of some California Aluminum Polish. The results are awesome!
It will look like this when installed.
I also fabricated up some sweet lower dash supports out of 1/8" aluminum. It really stiffened up the dash.
