I gotta say installing this large oil tank is a PIA. First just getting it up into its saddle requires a lot of finesse. You have to try a number of twists and turns to get it up in there. Then the rubber bumpers fitment is big fun, I used a rubber lube to get it to work. Center bolt went in ok but the tank just seemed to sit funny. I tried to install the lower bracket to the frame using plastic pry bars to adjust it. Finally I had an of sorts fit but when I tightened the Center bolt the tank slipped out of the rubber bumpers.
Of course I contacted Gary Edwards for advise. He had the same problem, suggested I make a new lower bracket with an off set hole to the tank. . How the factory did it is beyond me.
Any comments on you guys restoring one of these would be very interesting
