RE spinning bolts - the plastic bulb housing (body) is the culprit. I had to take the gauges off and pull it all apart. It looks like the anchors are molded into the housing and it just fell apart around them. I've just ordered a new one from Harpers for $5.80 p/n (02 76 63 00) Seems too good a price to be true, so double check p/n with fiche. I'm taking the occasion to refurb the dash - rubbers, speedo cable boot, etc. I also noticed where water has puddled in the back of the housing. Maybe I will drill a small hole at the bottom of each side. ?
