sorry about the multiple posts, it wont let me for some reason put them all at once, also if you cant see it in the pic, theres a cross brace in the back, as well as a 2X4 runnin through the center of both the top and bottom braces. The sides are also 2X4s trimmed a little so the 55 could fit. Also I know the paint isnt the greatest so i might redo it, and update it with a piece of wood that hangs underneath the ninety before the 55 which then slides up like a garage door (like the ones at some dealer tanks) to help it look nicer.
Also if you want more pics of certain areas let me know. Thanks
