Hey, I run a school bus dealer parts dept. in Little Rock Arkansas and buy all my a/c parts and units from a company in Dallas Texas. The name is Omega Enviromental, and talk to a guy by the name of John Hardie. I have yet found anyone to beat his price nor quality. They are an oem supplier for Blue Bird bus and other companies , plus John will bust his butt to help. The have a massive interchange and John can figure out most anything by pics or verbal description. They also have a web site.
