HELP...while trying to get to the fuel sending unit (thru the trunk floor) I could not get the trunk open..I have two (2) keys but neither one would work. I'm now going to try dropping the tank from the bottom to get to the fuel sender but how do I get the trunk open. I know I'll have to replace the lock cylinder but how to get the trunk open is the current problem. Can I just put a straight screw driver in the slot and twist (breaking it). I sure I can't get to it thru the back seat...Any Ideas ??  Thanks                                 '56 Ford Victoria                                                                                                                                                                             Jim Dahl         Washington, Ia
