The later AOD/AOD-E used that o-ring type fitting, I agree I also have never seen that on a C-6.

Usually has this 90 degree fitting but maybe cooling lines are not original.

6768 uses that straight in fitting. The 90° fitting came in to play very late 68 and into 69

I have a couple V6 parts transmissions around. Let me look my day and see if any have that feeling.

On a C6 the rear one has a 90 degree fitting like that while the front one is straight and just adapts the screw thread on the case to reverse flare thread found on the fitting.


Usually has this 90 degree fitting but maybe cooling lines are not original.

Ok, so I got bored offshore and looked through a few supplier catalogs for hydraulics.

Cheapest and easiest for this assuming 1/8npt to 5/16 tubing:

Thanks Randy!

Drew, I don’t think they are NpT threads….

Drew, I don’t think they are NpT threads….

The dozen or so c6s I’ve rebuilt were npt. Maybe Shelby cars used something different?
My Galaxie and F100 both run full roller c6s I built. Both run AN hose, I used 1/8npt x -6 with no issue.

Check the one you get from Randy, curious about it.
Thanks
