Dale, You might want to look into some Earl's, Aeroquip, or Russell A/N fittings. They have just about any combination of thread sizes you can think of.
If you look at the engine pics on my page, you can see the A/N fittings coming out of the front of my intake. I have the same thing (only straight) on the passenger side of the water pump. The big difference is the Vintage Air setup uses the same size (5/8) for both supply and return on the heater core. cYa- Herb Lumpp 1966 El Camino, LS6, 6 spd, Currie 9" ACES 3509 http://users.adelphia.net/~hlump/ ----- Original Message ----- From: "396guy" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, July 03, 2002 5:38 PM Subject: RE: [Chevelle-List] Heater hose sizes and connections > Confused?
