I've been looking into this for my 67 for a while. I'm leaning towards using a 69 Camaro gas tank that is already set-up for EFI. It mounts in the rear under the bed. You will need a sport bumper and a fold-down license plate, but you do not need to cut your bed for a fuel fill. There are a couple threads on this in the forum.

The downside is that you're limited to the fuel capacity of a Camaro tank.
