So I'm working on my basket case, and sorting through all the parts I got from the PO, and there is no gas tank cover or seat brackets of any kind. This is a 72, and the toolbox on the drivers side has also been cut out. I have some pro-car seats that he gave me with it, that have their own sliders, and I could fabricate some brackets for the drivers side, but how did the stock seats mount to the gas tank cover? Did they all have a gas tank cover? Do I NEED a gas tank cover? Do I just fabricate both sides? I saw a tank cover and a passenger side seat bracket on Ebay, are they all the same?
