Yesterday I met a guy that works on older Ford trucks like mine. We started talking about parts and I mentioned my cluster back had mostly turned to powder. He asked what would I give for a used one...said he had 5. Only problem was I couldn't tell him which one I needed so he looked at speedometer and said he might have one. Any ideas on a fair price. I see on LMC that they sell for around $60. Thanks for any ideas. On a side note I found an older sander/buffer/polisher in a Salvation Army store. I know it's older because it's Montgomery Wards Power Kraft. Works fine but I'm not sure about sanding discs. Bought some 6 inch disks at Harbor Freight with an adhesive backing. Any one know if they will work...they need to stick on a foam backing plate. Thanks for any ideas.
