Does anyone know the actual part number for the nut, that goes on the inside of the sheet metal for the body connection of a compensator arm? This is a 99 civic SI. And the nut itself is the one that usually gets stuck and falls in the metal. It is this one in the picture below. I need it bad... Mine are totaled. Rust owned me. If no part, is there an alternative? Thank you very much, this is a very urgent need of mine.

 

There is no part number, because you can't buy those from Honda. They are pretty much non-replaceable, since you have to cut holes in the chassis to access them.

Your only option, if you can't find a similar piece at a hardware store, is to cut into another Civic at a self-serve junkyard to pull a few.

 

i'd just get a stainless steel metric nut from a hardware store and weld it onto a plate the same as the stock setup
