81-87 chevy c10 owners

[mamato2]

OK - tried all the websites that were suggested here. I still cannot find a rear stepside fender with the fuel tank door on the drivers side. I did some research and I believe that the c10 had the fuel tank on the passenger side from 73-80. Then from 81-87 they switched it over to the drivers side. And from browsing pictures here, I have seen a few trucks with the fuel door on the drivers side. Has anyone that has owned a c10 between 81-87 ever had to replace a drivers side fender with the fuel door? If so, do you remember where you bought it? Thanks!!
