Center Hub Caps Loose - Need special washers

[mark97213]

I'll pay someone well for a solution.  different model Silverado.  The problem is and although the Front center caps fit perfect, the rear center caps fit too loose.  About 1/4 inch width too loose.  I need some way to eliminate the 1/4 inch gap from the screw on plastic cap nuts.  A set of washers, spacers or shims... something that can fit around each plastic cap nut that still fits down in the well of the cap.  Similar to the lock washer in the picture but with a wider inside diameter which will take up that slack.

can you get washers at hardware store and drill them out , i think body washers should be big enough

[mark97213]

That's an idea but I don't have bits nearly big enough.  Probably need around a 1" bit but that would be a tough drill set up.

stepdown drill bit would be perfect,
