I did some researching since we last chatted and found out that Specialty was a distributor for Crown Automotive, which all they do is Jeep parts and they don't sell retail. Their website had a list of distributors and the next nearest one I found is Capitol Jeepers Supply in Sacramento. There are also places in Tulare and Oroville. I'm going to try calling Capitol Jeepers and Surplus City (Oroville) about my gas filler tomorrow.
BTW, I'm going over to get the '64 Sat morning.
