John,

 

Summit Racing also has the small caps.  They are not any better than the ones at the auto parts store, they just have a good variety.

Thanks for the input on the pressure caps, I'm hoping to find one that fits the Mazda thermostat housing neck (small size), as I have this already shortened and installed.  I'll call the Mazda speed shops Monday, I found several phone numbers on line this evening.  JohnD
