OK, pics of the brake booster done
First is what i was dealing with, the picture is deceiving, because the valve cover had about a sheet of paper clearance between it and the booster.
Second is what i had after the work slotting the holes and switching to the smaller booster from a 1 ton truck. Yea, thats some snow on the cowl of the truck---god it almost kills me to have to put this outside for most of the winter, but a paying job in the garage is worth it.
