The gas tank for your car is the 1951-55 Kaiser type and yes, they are available from the KFOCI. Price is less for members who contributed their $10.00 to the Manufacturing Fund compared to non-members. The fund still should have tanks for 1047-50 model year Kaiser and Frazer as well as 1951-54 Henry J and Allstate automobiles and the Kaiser-Darrin.
The tanks are made out of stainless steel and I believe they also come with new mounting kits.
