hubcap locks

How can I take my hubcaps off of my 1979 fleetwood if I don't have the key for the locks???????

there are tools that you can buy that helps remove the gm hubcaps. I'm not really sure what's its name. anyways, I'll ask my friend who bought one before, I'll posts it here as soon as I talk to him. sorry not enough help for now.. 

Hello there:  You can drill the center of the bolt with a 1/4" bit and then use an easy out to remove the bolt which means you would need a new set of locks if you plan on using the same wheel covers or you could ask another caddy owner to see if his wrench fits your locks. Good luck mate.
