Get hold of a Holdens c/log or their web site ( plenty of dials to see ) the 4 small are dials are all 52mm on your mog . You dont need the dash out its easy to swap just one dial and yes you can use the same or original electrics .
Following my weekend drama with fractured oil lines, I am keen to delete the oil line and swap to an electrical pressure gauge, there seem to be a few on the market. My car is an 88 cvh, with tudor dials (52mm? - I haven't measured them yet!)
I would appreciate any tips regarding whether one make or another are better in terms of durability, ease of fit etc, plus any pearls regarding the fitting would be appreciated. Would I need to take the whole dash out or can dials be swapped with it in situ? can I use the existing electrical connection to the existing dial?
