Hi guys,

I'm installing factory a/c in my 85' lwb sierra and I'm after some measurements of the holes in the firewall (accurate size and location of the holes). I believe all w/t leaf sprung model sierra's had the holes punched in the firewall from factory. Any help would be much appreciated.

The holes I need to drill


What I have at the moment.



thanks.

It might be easier for someone to measure the location of the holes without a/c installed.

I wonder if those center punch like indents in the firewall that are there from factory are the location of the holes? Could anyone confirm this?

Thanks Mick

I've found some good photo's on the net of the holes that need to be drilled. I'm going to give it a go in a few weeks when I get some time. If it doesn't go to plan I might give you a call and come and take a look at you black one
