Correct Max Wedge Radiator cap

[skyman51]

I posted earlier about removing calcium deposits from the radiator fins. This was leaking from the cap under pressure. What is the correct radiator cap for restoration purposes for a 1963 Max Wedge? Where can I get one? Thanks

OK, let's forget the max wedge in the description. Is it one radiator cap for all and what is it? How may pound cap?Thanks
