Help! 1982 corvette knock sensor

[82ed]

I need a knock sensor for a 1982 crossfire corvette. The stud that goes into the wiring harness is broken.

You will need good luck to find one. You need Pt no. 1997463. I have been looking for one for three years with no luck so far. I have an early C4 one fitted but no sure if it works. If you find one let me know, thanks.
