brake pedal bushings

Talked to Brewers about their brake pedal bushings. I guess there are 3 different size pins retaining the brake pedal. The small, approx .500, the heavy duty .109 and then mine, .810. The large and small are both available from brewers but it seems the .810 pin bushings are nowhere to be found. Bought a pack of replacement bushings from the parts store but they are also too small. Surely I'm not the only person to have this problem. Does anyone have any experience with this?
Thanks, Wayne
