How bad is this? Idler arm frame mount
 

Attachment 37916putting ina new idler arm today. I saw this.
2000 Blazer 4x4

looks pretty standard to me.

Surface rust, should be fine.

So those bolt holes aren't stripped out? That's the way it is?

They are not stripped, the idler arm position is adjustable. You want to make sure and have the centerlink parallel to the ground minimize wear on the front end.

Ah thanks. I was worried because I couldn't fit the bolt through the top of the hole there.
