Brand new idler arm, lots of play

I found that I needed to use washers to shim it tight. The pivot bushing was fine, it just had too much free play on the bolt. And to answer the question, yes, I have a 67, but it has a reinforced 68 K-frame so has the through-bolt idler.
ya, looks like a washer to shim it may fix it, the bushing is fine. As far as the old one, it was worn out so i didnt pay much attention to it.
