| Da {Bernard Day - Chassis Design} /Hdy {William Hardy} 1/M22.4.31 contd. -2- With regard to Delco dampers these may prove to be 100% as you suggest but we certainly have not yet had sufficient experience to know that they are. We know from experience with our own productions that months of usage on many cars are required before we have full knowledge of their performance and failings.
