Does anyone know where I can get a replacement water nipple for the heater core that connects from the intake manifold to the heater core? The only ones that I can find do not have the same configuration with the exit hole being to big and not the same as the original. Any suggestions? This is for my 1971 Cutlass SX 455 V8. Thanks for your help.

I moved your post to parts wanted. I'm sure someone has one on here.

To the best of my knowledge, all heater hose nipples, at the right rear of the intake, are 5/8". There are two different size pipe threads where the nipple threads into the manifold, depending on the model year of the vehicle. If this is the problem that you are having, I should be able to help.

In the early 70s I bought some from the Olds Parts Dept with different restriction holes. All were steel with the screwdriver notches in the top, and 3/8 NPT thread. Is this the type you want, and which hole size?

Great. The whole size is 1/4 on the bottom. That is the exact one I need. Let me know if you have one and how much. Thanks.

Thanks for the info. Picked one up from Fusick.
