We have, in quite a number of cases, found it necessary when dealing with closed body having the Scuttle entirely isolated from the dash, to couple the two together by putting bolts through from one to the other. This has been necessary on account partly of the excessive sideways movement of the body, and partly to the fore and aft spring of the dashboard, and in every instance when the two have been coupled together there has been a marked reduction in the knocks audible when driving on a bad road with no apparent increase in the tendancy for booming.
