look at the this and the next few photos...

how the baffles are installed...  

most of you know i am a terrible back seat driver and others will realize i am a forward thinker...

my thinking...  the baffle sections need to be cut larger... and the edges rolled more than 90 degrees... so the edges of the baffle plates are have a J shape...   careful punching of holes before rolling will let the fabricator weld the baffles into position through the bottom of the J   this way.. there will not be any little tabs that can break off..

i think i would also position the tube thats installed through a hole in the baffle.. the hole bent to an angle to allow the tube to be supported tightly... instead of bracketed...

I make the baffle about 3/4" oversize, on all sides, and bend a full flange that welds to the tank. I also fasten any tubes to a bracket inside the tank so it won't vibrate and crack.
