I admire you guys in the 'orange cone club' for your perserverence, but I would suggest that unless you REALLY like to constantly tinker with those vacuum steps that you replace them with a comperable model from Kwikee. They make a great product and if installed and maintained properly, work without fail every time. (no I didn't get paid to write this) <G>
