| - 2 - good clearance could be allowed to prevent rubbing and squeaking, and unit No. 3 the remainder of the body to the rear. Any objection to cutting through of the body, as suggested, can be overcome by using the type of doors now becoming popular, which run down the full depth of the body, to the level of the top side of the chassis member, or even lower. The Steering colum could be attached to either of the dashboards, or both. If attached to dashboard No. 1 there would have to be a clearance hole in No. 2 dashboard which could be prevented from passing any hot air by fitting a large rubber ring between the two dashboards, similar to the old water joint connection between the cylinders of the "Lanchester" engine and others. By making many apertures in No. 1 dashboard a great deal of the pressure of hot air could be relieved. | ||
