110139 body to chassis fixing drawing
"Fixing" is the British term for the "action of fastening something in place", which is what is illustrated in this drawing - the attaching of the fiberglass underbody to the epoxy coated chassis. Notice in the list of items required in the upper left corner of the drawing that Item #6 is "Tivoli Kay", the brand name of an adhesive used to secure the sealing cap. It should be noted that very few cars appear to actually have had the cap fitted in this position, presumably because of the periodic need to check the tightness of these body bolts that would be covered by these caps.
