Pics of '68 and up A-body fuel tank mounting??

Hi,
I'm putting by '67 Barracuda back together and getting ready to install the fuel tank. My car only has 1 strap to hold the tank in, and it doesn't seem like the safest design. I want to fabricate the mounting tabs to convert it to the '68 and up 2-strap design. Does anyone have pics of the mounting tabs that are attached to the trunk floor? And how are the straps mounted at the front?

Thanks!
Scott
