I'll look to see if one is available.  I was also thinking about th= e overflow port and feeding it into my expansion tank - thanks, I'll seriou= sly consider that as well.

Jeff,

On my radiator, I = have a solid cap, no pressure relief. This cap seals at the top of the radi= ator neck, not down at the bottom where the pressure cap seals. That allows the coolant to rise into the overflow neck= . The overflow neck nipple is then plumbed to the bottom of my swirl can an= d the swirl can has a pressure relief cap on it. I think 21 lbs on the pres= sure relief cap.

This system automa= tically eliminates air and I periodically check the swirl can to see if I n= eed to add coolant. I only have to add coolant if I have had the system apart for maintenance and introduce air.
