Here you go...

Ford, Chevy, chrysler & dodge, and everybody who used an upper controll arm like what you see on yours, (and there are a lot of 'em) used those shims an nearly every vehicle out there, and yes it's to make everything align up correctly. I've seen them on chebby truck upper controll arms as thick as 3/4 of an inch on the foreward edge and as little as an 1/8th on the trailing bolt... some Mopars foresaw this problem and put in ovaled washers on the bolts on the front and rear to compensate for using shims... It all stems from the way/quality and machining when building it, like Phat said... and to set the caster and camber like Mosnster is going to say in a minute or two...
