any body tell me where the cab jack bar is normaly kept on a series 2 fh
should be in a grey plastic wallet along with a wheel brace, and a small silver right angled socket which fits on the cab jacking point (nearside front corner panel).
This should all be at the back of the nearside stowage locker. Failing that, will be in the fitters toolbox in the garage.(they could teach Magpies a thing or two) 
In a grey bag in the n/s side locker along with wheel brace and screwdrivers. However due to the age of your truck it may have gone missing by now. If you have the electric cab tilt pump like all mine you only need the angled socket to open the valve and work the switch. For a manual pump you need the angled socket and a long handle.
