Mark, I've got a 19' Miller Bubbble Deck like the ones Tom has been working on. I used that chart from above and I think I can get one from Cabela's for around $160.00. For about the same thing, West Marine wants $415.00. I've got the frame that came with the boat but one of the tubes is bent. I haven't really looked at it except to notice that someone burned some holes in it on the headers.
