Finally have my own tank mounts in production mode! These are similar to ones i have made for my own tanks. They are 6061 aluminum, wider than some of the other steel ones I've seen, and super deep. This makes them easier to install in really round tanks, but they are good for flat bottom tanks too. They have steel straps, with billet aluminum caps for the rubber gromet. They also have a true blind tapped hole, not a thru tap with a shitty spot weld on top.
