Thoughts on this tank install?

[junior11]

So I have done some work, I put the pictures of what my coffin looked like after I removed the fuel tank first. Since then I gel coated the entire area, put in a bulkhead, cut the tank down from 175 to about 105, and have just put the tank back in. I attached some .223" lexan to the bottom of the tank where it sits on those platforms. I then hammered some starboard wedges down the side and made those pieces you see going around the brackets to hold the tank from moving up and down. The tank fit very tight without putting those wedges in, and it can't move front to back at all, it barely fit back in. Anyone have any thoughts on using the starboard to keep the tank from moving?

Also, my doghouse is almost ready for it's roof. It is getting its camber as we speak.
