O ringed waternecks
 

Anyone have a source for an o ringed waterneck, correct for 67 GTO? I'm looking to do some thermostat testing, and an o ringed version would make it easier.

By correct I just mean angled and able to be swiveled to the appropriate location. I dont expect to find a repo one with an o ring groove. Though that would be cool...

Try amazon prime Spectra Parts. I hope that this can help. Thanks Bob.

Have you used one of those? Looking more for a recommendation. I'd like to get one that someone has had success with. I've seen enough of the cheap ebay stuff for Chevies and such...

I use, with success, a cheap ebay swivel housing for a Chevy. The bolt holes need to be elongated a little to fit Pontiac but otherwise fine if you want to try it out cheaply.

Thanks, appreciate the info.
