I need a water control valve for a 69 b body with air conditioning ,this is the valve on the firewall where the one heaterhose goes in and it comes out going into heater core ,its leaking ,don,t have a clue where too look for this part ,iam sure its non existinct at part store ,thanks

There is a couple of places rebuilding them, and maybe some NOS parts out there..
Other cars (GM) used a similar valve...
On a previous post some said NAPA has a repair kit for them as well.

Check RANCO valves on the internet

here is one place

Try Joe Hudacek. I think he is more reasonable.

Find a good RANCO core and send it to Classic Auto Air and let them rebuild it. They charge around $150 to do the job. I had two done and they turned out beautifully.

I bought a part like this off eBay that was defined as NOS. It had a copper wire scabbed on instead of the actual capillary tube and did not include the bracket that screws into the heater box... just a long length of copper tube that ended up breaking in two when i went to unwind it and try and get it to work. Clearly not NOS. The part lasted about 5 miles down the road, leaked and overheated my car during proving run. Just an FYI for parts called NOS that sometimes do not end up being that. Also, the part shown on the link above has been used to advertise that NOS piece for the last year or two. That always makes me wonder just what I could end up with. As few and far between as these assemblies are supposed to be, you'd expect to see an actual picture of the part being offered... unless of course, this particular NOS water valve has not sold in over two years. I guess that is possible too.

Napa has a repair kit .It is about $10.00

NAPA repair kit is just a replacement rubber seal
assembly, part #6601000
