MG T-ABC

I’m missing something trying to remove the gas tank. I can move it, but it looks like it is secured into the fenders were the two rubber bushings are on the side of the tank. I hate trying to force something. I removed the straps and the spare tire carrier along with the fuel line. I’m missing something. There is a bolt through the fender well. I thought that just held the rubber bushing in place. Does it go all the way into the tank? Are there some other hidden bolts or am I just not pulling hard enough?

There is a captive nut that the bolt threads into on each side of tank. The Moss catalog can be of use to show this.

It turns out the "builder" used studs instead of a bolts to attach the the tank to the fenders. I resorted to the double-nut technique to extract. Now it's off to the repair shop.

Split pins to hold the bottom fuel tank pads to the frame?
