Would anyone know what thread the upper and lower diff cooler holes in the diff are? Seems they are an odd size that no one here has ever seen!
This is the lower fitting - which I also need as I am going to try and adapt a different oil cooler setup, after the shippers jacked my car up using the cooler as a jack mount.......

Have taken it to a machine shop and it does not match any of their thread tools - not even close!

Apparently it's not AN or NPT and the thread is different from their metric gauges so who knows where Maserati got this from.
