Gas tank question

[Shak]

I am considering using either of these tanks for my 67 rebuild. Has anyone ever used them and if so how did the install go. If nobody has used them does anyone have any advise about the tanks or the vendor. This board has been a great source of inspiration for me and I appreciate all the experience and advice I've gotten. I am trying to keep costs down, and I can get either tank for about $215.
