Master brake cylinder

[SFcarbuff]

Which is the correct master brake cylinder for a mid March car?  Is it B2225032 or 2225032.  I believe a 2225032 is a Corvette one which is slightly different.  Any help is appreciated!!

Ether one of those casting numbers will work on a 65 or early 66 but you need the later 66 style that has the flare fitting seats made into it. The others have pipe thread and need a brass adapter between the master and the brake line fittings to seal . Fortunately in your case that one with the flare fitting seats made into it is the only kind that the after market makes. The after market ones that I have seen look the same as OEM except that they de not have a Bendix trademark on the bottom and Julian date code. I don't remember if they have the casting number the same as assemblyline or not. You can't see any of that once installed anyway. The ones that need the brass adapters are the harder ones to find but again not right for a mid March 66 car.
