Aluminium AST Cap - which one?

[Kash_]

I\'m looking to buy an aluminium AST, which looks like the picture below:

The problem is that it only comes with a 1.1 bar Cap.... does anyone know where I can get a 0.9 bar Cap which will fit it...? Will the standard AST cap fit?

Try it when you get it, you cant tell from picture
