which efi fuel tank?

how did you make the access plate? it looks like the a-body tank has the same kinda contours as the b-body tank in that video?

my main motivation is that i wont have two lines connected to the fuel sender to possibly tweak the sender/housing when the body flexes.

what brands are the tanks though? rockauto has the spectra tanks(which from what i've found are made in canada and have a good reputation) for $165 plus shipping. I don't wanna cheap out and then be fighting this leak all over again.
I bought a new A body tank off eBay from http://myworld.ebay.com/tomsclassic According to the sticker on it, it was also made in Canada. I scoped out the fuel pump/sending unit and planned on where I thought it best to make my access hole. Then I used the old gas tank from our '68 Charger as a donor for the metal we used to make our door. Luckily we hadn't disposed of it after we'd bought a new tank for it.
