Project: Tetanus Shot - 1948 Willys

Got the seat frame fully welded up and installed. The tank fits and the tailgate closes.

Now the fun part. If I go off the original mounting holes, the tank makes contact with the back of the seat and it would be difficult to make the mounting straps work. Seat is secure and doesn't move and the tank wouldn't move but I'm wondering if it would eventually rub holes in the back of the seat. If I scoot the tank towards the tailgate, I have a fingertips width of space between the tank and the seat but I would have to drill new holes(which normally isn't a problem) but I would be drilling through the rolled edge of the tub and wouldn't be able to capture a nut on the backside. I could always spot weld the mounting bracket to the the floor but then I'm left with how to properly secure the tank. I could always weld some bolts to it and see if the mounting straps would work but I'm also thinking of rachet straps or something similar.

Thoughts and opinions please. I remember reading that not securing this tank with appropriate mounting brackets leads to some issues like split seams.

What about some metal straps from the bar above and rubber bungs to align and stabilize at the bottom?
 
I currently have this bottom plate for the tank

and I have these straps from Motobilt

As you can see from the photo, I can't push the mounting plate to the rear and bolt it down. I could weld it down and then weld some bolt studs to capture the mounting straps. Or I could weld some loop tabs on the mounting plate and run some metal straps or similar to secure.
