I bought some used kegs off the web and they are the pin lock style. I am already set-up for ball lock and dont want to use both styles, so wondering if anyone has had success with swapping out the posts? It seems the lids are universal but not sure on posts All my ball locks are full and I dont want to disassemble them, also dont want to order more stuff and find it un-applicable. http://www.kegoutlet.com/corny-keg-posts-poppets.html Thanks !!
