Hi all.
I have a 90 with a 3.9 Efi v8 in and lt95 with air diff lock. I have recently put the 3.9 in her and was wondering about the diff lock and where I can pull the vacuum feed??? Am I able to T into the servo to pleanem chamber hose for the vaccum feed?? Or is there anywhere else I can use?
Many thanks Dave

Are you sure the diff lock needs vacuum and nnot compressed air? You could always fit a vacuum pump. Depends how strong a vacuum it needs.
