Hello, when installing a new CTS the boss that it screws into cracked (I don't think I over-torqued it, was a small wrench and the part was fairly corroded). Does anyone have the specs for it? (inner-outer threads, other specs) I can't find anything about it online.
(image taken from sensor locations page on The Fiero Store) This thing ^ It's not labeled here.
If anyone has any info please let me know!
P.S I am currently looking for excuses to 3800 swap. This could finally be it.

The adapter fitting is an off-the-shelf brass plumbing reducer fitting.
It has 3/8" NPT threads on the inside for the sensor.
It has 1/2" NPT threads on the outside which screw into the lower intake manifold.

Cool! Glad its a general part. Was worried it would be hard to find. Thank you!
