Bought our 1973 Ambassador on Ebay and the nice folk delivered it to us, letting us know after payment that they while they had the title, they did not have the keys. It was dark out, and we didn't think it was any big deal, being totally inexperienced and not planning to go on the road for quite awhile, only to discover the next morning about all the compartment doors and the need to open them. After reading of the difficulty in getting key blanks even if a locksmith was obtained, I broke down and drilled them open. Now I'd like to put new cylinders in, but apparently you can't get the old ones out without a special key? And I haven't found anyplace selling just the keyed insert piece which could be fitted into the main locking piece with the spring on it and squared off screw. Any advice out there? Too late to tell me not to be so darned hasty!
