Ok but ball lock posts will fit onto a corny keg no worries right? I have a corny and filled it with my first beer the other day so have never taken the posts off and therefore dont know what it looks like on the bottom threaded area.
I then recently scored a Schweppes keg for $30 and did take the posts off. They seem a bit old so was going to replace them with corny posts..if they fit. And as your all suggesting where I can get them I assume they do.. Which I can probably get them the next time I go to keg King
