Greetings, Weather is finally cool enough that I can work on my '67 without risking heatstroke! Thought I'd swap out the tank with the new EFI tank. As I was uninstalling the existing tank I noticed 4 holes at the front edge of the tank...thinking "now why didn't the shop fill those?" It wasn't until I removed the tank that I realized these look like bolt holes for something...thing is I have no idea what these would be for. Why would they be half under the tank lip and half exposed? Doesn't make sense to me, and I don't want to leave holes in the floor. Any ideas?
