I decided to use the Powder Coat gun I got for Christmas a couple of years ago from my wife. Picture 1 show's what I started with. I wire brushed the spindle and caliper bracket to remove the surface rust and cleaned it with lacquer thinner. I sprayed the powder on and let bake for 20 minutes in the oven at 400°. Picture 3 shows the parts back on the car.
Because of the odd shape of the rear crossmember, I had to use some rectangle tubing and cut it to fit in the crossmember. Once I welded these in the tank brackets I made could sit flush with the crossmember.
Rather than spend $800 on a stainless steel replacement tank for my car, I took some measurements and found that a 16 gallon tank for a 1953/54 Chevy would fit. I purchased it from "Tanks" for less than $300. I made some brackets to mount it in the original location. These pictures are when I was fitting the tank.
