1982 Knock Sensor
I have an 82 corvette and ofcourse can't find a knock sensor. The one i have on the car has the stud that the plug connects to broken off. Has anyone tried repairing theres? Like maybe drill and tap and put a small all threaded stud?

The stud is potted and very small.......I do not see how you would repair it without damaging the potting.......if there is any of the stud sticking out...maybe you could sodler a non-insulated butt connector on it.....
The sensor is unobtainium too.....N/A anywhere....out of production......I sold the one I had off my Ex-CFI Z/28 to Buccaneer..LOL.....
Not sure if he has figured out a solution yet but wouldn't hurt to contact him.....

From what I've read, all ESC modules work the same. It's just that the knock sensor is tuned to the particular engine along with the corresponding ESC module. I never tried this but I bet if you got a knock sensor, ESC module, and the harness from a junkyard from 350 TBI truck and wired it in it would probably work.

They make a wide variety of different Knock sensors for the different frequency noises that come from the engine. If you can get the specs of the knock sensor you might be able to track one down. If you can get the factory Part number as well you might track one down for less than that EBAY joke for $500
I still have a MSD Knock Indicator that uses a standard $25 knock sensor.

One thing I would like to add I used a 92 ECM with a early 82 knock sensor/ESC with out issues.

I had a perfectly good one that I broke when I pulled the engine for my TPI swap. Oh well

You're on the right track regarding the possibility of a separate/new harness using later parts to replace some obsolete hardware. IIRC some of the later truck ESC parts are the same calibration as used in the L83 and L98 engines. I have a standalone ESC harness with this calibration (and others) that I wired up to detect knock on carbureted engines. (Instead of the ESC module sending a signal to an ECM, I just have some circuitry that will drive a bright LED that is visible to the driver.)

One thing to keep in mind is the early 82 knock sensor was a "microphone" type. Later knock sensors were a piezoelectric type. That's why you can't just swap a later knock sensor into the early cars ESC.
