Not as easy a question to answer as you would think. I need to find a replacement drivers side fender (stepside) for my 83 c10. My fuel filler door is located on this fender. I have literally called probably 50 different places = everyone makes the aftermarket fenders with the fuel filler doors on the right. From what i understand, from 73-80 the gas tank was on the passenger side of the truck - with an option for dual tanks. Then from 81-87, the gas tank was moved to the drivers side. But no matter where i've looked, i cannot find an aftermarket drivers side fender with the fuel filler door. Anyone had to replace one yet?
