<VV> Dual master cylinders and bench bleeding

[Jim Simpson]

I'm not sure about the exact origins of the master cylinder in my car ('66 
Corsa converted to dual master), but I pulled it from a '69 that was being 
junked.  Took the entire package -- bracket, lines, differential pressure 
switch, etc. -- including the master cylinder.  This master has bleeder 
screws right at the outlet ports!  I didn't have to fool with bench 
bleeding or any other such nonsense -- just bleed it at the ports and got 
all the air out of the master cylinder then when around and did the 
wheels.  Worked just fine, even with DOT 5 brake fluid.

Now my question is, did any Corvair come with master cylinders with bleeder 
screws?  Or is this an aftermarket replacement?  In any case, it works just 
fine.
