Re-Installing Tank on 67 Barracuda

Yes, those tamperproof screws are a pain in the ***. They were designed that way. They do make a kit with a tool and 3 new screws, but I just pulled the old ones and put in conventional screws. Nowadays, thieves aren't interested in gas caps, they just go for the whole car.
BTW, I had no idea how to get out those awful triangle head screws, so I PM'd Redfish. He said to use needle-nose vise grips. As usual, he was right on. Thanks Redfish and thank all the other members on this Forum will to share their knowledge!
