Does anyone know right off what size body bolts I need to install a new air dam under the radiator support? Mine was completely missing and I don't have any old bolts to reference to get new ones.

1989 RS is that matters.

Thanks

 

Should be a #14 screw.

 

The center 4 were all messed up so I drilled them 1/4" and used bolts and nuts.

The outer two I used some big TEK screws through the damaged nutserts.
