Sounds like a lot of fun Mike. Having done quite a few over
the years I have my own little things I like to do. On the one
in my current Westy I used little bushings on the ends of the
heater flap rods. I don't know what they were made for but
I found them on the shelf of our Truck repair facility at work.
I used a "plastic welding" technique to hold them in place.
I needed to replace all the foam and the body to box seal.
I used Allen bolts to replace the Phillips head bolts. With one
of those ball tip Allen bits you can buy them from just about
any angle. I also used sealer on those bolts on the threads
and on the end reached from the outside through the grill area. Keeps them from rusting and leaking.
I replaced all my cables last time and it proved to more work
than it was worth. Plus upon examining all the old cables they looked to be in fine shape. It took a bit of fussing to get
them all adjusted just right. Now when I drive no air goes
where its not supposed to. Keeps the heat out in summer and cold out in winter. Before I always had outside air making its way past somewhere in the box and I wasn't able
to seal off the outlet directing air to the feet.
I noticed that on the drivers side of the Westy that I had these vinyl bags sealed up with foam inside blocking the air
passage that feeds air to where the roof vents are in a passenger van. They had started to fall apart and the way they settled was in a position that would whistle when trying to direct air down the vents on the passenger side roof of my Westy. What I did to
replace them was cram a heavy duty plastic bag with the open end exposed in the hole. I then squirted some low expansion foam into the bag. Tie wrapped the bag shut and
pushed it in a little bit more. It sealed that drivers duct perfect
and no longer have a whistle. This duct if I wasn't clear is on
the a-pillar and on a passenger van would feed air through the front doors to a opening on the B pillar that then feeds the vents up along the roofline. A Westy doesn't have the Vents on the drivers side because of the tray that runs above the sink/stove cabinet. Those bags of foam that were falling apart were installed at the factory to seal off the drivers side.
GoWesty has an article explaining a bit about it:
