E.CD.1014. 1360 file Further to our memo DA.{Bernard Day - Chassis Design}24/G.10.11.38, we have now discussed with Messrs. Metalastik which of the methods indicated in Figure 1, of E.CD.1014 they would prefer from their point of view, and the method chosen is the one with the greater thickness of Neoprene fixed to one face of each half of wedge, using standard wedges.
