Do a search on ebay, it's where I got mine for my '56, 3 years ago. Can't remember the name of the guy I think he's in Minnesota but he posts stuff frequently for mid 50s Fords.
Do you think there is a difference in quality of the tanks listed on EBAY between different vendors on Ebay as the prices are different between vendors ?
I see one for sale in the LA CA Craigs list, Says he got rid of the car and this is left over, Has guage and straps, I will look for a link, http://losangeles.craigslist.org/ant/pts/2547256414.html
Found it it's Lancaster Ca. Not sure where you live, but this has been for sale for a while, might be open for an offer. Gerry
The company in Minnesota is called Auto City Classic Glass, 1-800-828-2212, Isanti , Minnesota. They go to all the swaps up here in MN, WI, IA. They have been around for 30 years, I have bought good stuff from them in the past, fair prices etc
I would try a company called tanks I got a tank for my 39 plymouth from them and I know they make a huge variety of different tanks for different applications
Thanks to all who responded...I have purchased a new tank from "KENNY`S ROD & KUSTOM" in Newton Falls,OH for $200. including shipping. Real nice tank and fits well....John in CT
