Hi,
opened her up this afternoon. As expected the cush drives were totally to shot. Did the old inner tube fix. Still was not enough. The fit was not really tight. So ended up with an extra layer of tubing between the metal dividers and the larger blocks. Nice and tight now but still fairly easily pushed together. See how it goes. As long as it lasts the estimated 2500 miles of the trip. Did not last that long from new afterall.
