Looks like your moving right along Scott. Have you looked at the Mopar perf. master cylinders? Their just like the ones used on newer Dodge trucks (92 and up?). I know the bodies are made smaller than the one you have so that'd give you a little more room. Not sure how much diff. the lines would be though. Maybe if you get out to the scrap yard again look for one and compare.
Don't get caught like that man. They'll hang ya. LOL
