Dang if you aren't rolling right along..........looks great. Your valve and switch will be fine that way. As for the brakes working with the wire wheels, yes you need the adapter that acts as a locating device for the wire wheels to sit correctly on the drum. Several people make these, like Rally America and maybe Wilson Welding. You said you bought a set for the back, so the same folks should be able to hook you up. If you don't use them the wheels tend to rock on the drums instead of holding firm.

If you need the bearing numbers and what mods need done to make the truck brakes work on the early spindles, PM me, I have it somewhere.

Proud of you guy, you are getting this thing done really well. The shiny stuff looks good on the engine too.
