Type of cap for aluminum ast?

Hi everyone
I wanted to see if anyone can point out the best cap for a aftermarket ast I have? Last week I ordered a Stant cap from mazdatrix, part#10329 and it's too big. I don't know which ast I have but it fits the regular fd thermostat housing cap perfect. My question is if it has to be lev-r-vent cap or it can be a regular 0.9 13psi cap?

It has to be a pressure cap. Lever vent makes no difference.

If it's the stock-type cap neck, I would just get a new Mazda cap. They're typically much better quality than aftermarket caps and they're priced reasonably.
