Hello all! New here! I am replacing the flex plate on my 2002 Monte Carlo SS and it's missing the cover, exposing it to road debris (how it got damaged in the first place). I'm trying to find the exact name or parts number so that I can order one. Does anyone know? Thanks!

 

Probably the best source is this site:

I tried looking but could not find it. My guess, the part has been long discontinued and you might have to get one from a junk yard.
