Yeah Im hearing you Agro. I thought I was smart and went for a mixture in my WB. Aftermarket compressor so I could get to the spark plugs and integrated vents and evaporator. But..... one of the vacuum servos has died (I think) and I have to pull the whole lot out to get to it. They must have had a Pom working at Holden when they designed that setup.
I am going to fit it to the Sandman as well. I am just a sucker for fitting Holden options. Am going for the full set up though.
