Re: 1971-2 brake master and booster

Yeah,I guess what I was saying is the parts will go together,even mismatched,but won't work right together. All the firewall mounting is the same through all the models. I believe if you posted a picture of the m/c you have we could determine which one you need. I see what you are saying about wanting a new m/c and wanting to be sure you get the same maker/design. Not sure there was any rhyme or reason to which one came on a truck,maybe just two different jobbers for whatever reason. I think at Napa they have books that show pictures,if you have a good store near you with someone willing to look that far into it.
