Hi all iam thinking of putting some gauges in the 3 door (oil pres, water temp and boost gauge) in the centre vent,i allready have a boost gauge on the pillar but will move this to the centre.what i would like to know is what is the best route to get the water and oil senders through the bulk head,and what is the best way to fit the water temp sender, ie weld a boss or into a hose many thanks paul
