Nice Job B'. Is the glove to be welded directly to the tank or will it utilize brackets in some way? In process of trying to get my tank mounted but still fighting on how high it should actually fit from the bed or frame. Looks like your mounts are mounted low on the plates so assuming the tank is a bit higher. What's your approx. measurement from the frame up to the bottom of the filler neck? Forget what your running for a body lift.
It's a 3/16" aluminum skid plate, it will be bolted up to the frame brackets. plan is to suck it up tight against the bottom of the tank with several small thin rubber pads strategically placed in between.
as far as mounting the tank, I have a 1" body lift and I used a piece of angle iron bar clamped across the top of the rear frame to jack the rear of the tank up against. I did end up placing a couple of 1/8" thick washers between the tank and bar to space it down slightly for filler neck clearance against the bed floor.
at the front I messed around with different spacers placed on the top of the tank until I achieved the clearance I wanted. with it jacked up solid against all that it was easy to fit the brackets.
Might be easiest if you just fit your tank on my Bronco as it really does come down to filler neck to floor spacing when trying to tuck it up tight. worst case scenario you would have to ad shims between the bottom of the frame and the brackets to space the tank down if it ends up too close to your bed floor.
