replacing power window motor bushings

I wish you'd posted something sooner that you needed these. I would have told you to use three 1/4"x20 nuts instead.
They are a perfect fit and install in place of the plastic ones. Would have saved you a few pennys.

You could have bought the plastic bushings (or rollers) at AutoZone. They would have fit without any rework and been cheaper too.

The window motor gearbox has 3 plastic rollers that are a safety clutch to prevent possible injury if the window is rolled up while something or someone is hanging out the window. The plastic rollers will often disintegrate into chunks of plastic and the window will no longer roll up or down. The motor runs, but the window does not move or only move a lttle.

The Help! section of your local auto parts store will have the replacement plastic rollers.
