Looks good Matt
I finally got around to getting a Buick Estate wagon master cylinder. The one I got has the shallow bore in the back of the piston, which should work with most boosters made after '70-'71. Did you find a source for brand new intermediate pushrods, or did you find a used one? I remember seeing them somewhere, but now I can't find them.....new that is.
Have you had a chance to drive your truck with power brakes yet?
