1966 gas tank placement

[boilermaker27]

I am in the process of restoring a 1966 Thunderbird convertible. I removed the trunk as it was pretty well rotted away. I am now in the process of installing the new trunk panels but have just realized that I did not take any measurements on the placement of the lug that holds the strap for the gas tank. I measured the top lug above the gas tank and it is 7 inches from the side of the frame. So, I know it has to be 7 inces from the side as it must line up with the top lug. What I do not know is where to place the lug on the new trunk panel. If anyone has any way to measure this it would be greatly appreciated. I think the easiest way to measure this would be to measure from the center of the rear axle back to the edge of this lug where it is welded to the bottom of the trunk panel. I don't think the gas tank will be in the way, the strap will be in the slot but if a measurement can be taken just from the front of that lug I think I can get it close enough. Big challenge and little hope of any results but don't know where else to go. Thanks

Get your measurement from the old gas tank. If you are buying a new tank, get the measurement from that one. The straps conveniently sit inside grooves in the tank.

So, even if you completely remove your trunk steel, you can still replace it. Use the tank dimensions and character lines for placing your attachment points.

The factory usually puts some sort of padding between the tank and the trunk floor. Use anything you like as long as it doesn't absorb water.

Also, ground your tank well. I drill a hole in a corner, away from the seam weld, and use a #10-24 brass or stainless machine screw with a nut. Then, make a copper jumper wire and attach it to your frame. Do not depend on spot welds and painted panels to conduct fuel gauge power back to ground. - Dave

thanks for the information. What you say about the ground is a great idea and I will do that. I see what you mean about the placement of the straps and attachment point. I never had the old gas tank but do have the new gas tank, but I don't have the straps to hold it in place. I am going to take a look around today at a few junk yards and maybe can come up with a 64-66 Thunderbird or Galaxie and climb underneath and get some kind of a rough measurement. I would like to get the attachment points installed before I put in the new trunk panels so I don't have to weld it overhead when I am ready to install the tank. Thanks you.
