Tractor Supply or Farm & Fleet or Farm King they may have the internal valve to convert yours.
I know Tractor Supply used to have them cuz I used to work there.
There were several different manufacturers. You would need to know that in order to get the right valve parts.
Thank you. I didnt think of that and I have an account there for farming. I will clean the valve off to get the manufacturer from it. About how much do you think 50 or 100 or ?
