I have a 1970 RS and am removing the brake master cylinder and booster. The booster has a 0426 on the back side of the top tab and a 48 on the front of the tab. Can someone please tell me how that breaks down and what kind of value it may have? It works great, also has the matercylinder, distribution block and pushrod with it. Pretty much everything forward of the firewall is intact and working well. There is a little bit of surface rust and also some black spray paint on it from a previous owner but is very restorable. Thanks for any help and info.

Lots of discussion about it here.

I am confused. That link just leads me to the same question I posted on another forum looking for the same answer. Is there a problem with asking the same thing somewhere else? I am curious. There is no book that I am aware of that lists values of these used parts. And this is the only forum I listed it for sale in.
I am new here and was just looking for info. It had no bearing on the price of the part. The for sale ad was placed first. I did not change the listing price either. Even after I found it was worth more than that.
