Hi all,

I have my new idler arm. However, the j shaped frame mount has grooving inside the bore where the idler arm taper would bolt. This leads me to believe the old idler arm rotated inside the mount at some point. I'd like to replace this frame mount part since I'm replacing everything else. Problem is, I can't find it or know what it's officially called. Anyone know the correct name and source for this frame part? I tried LMC since they have nice diagrams but it's grayed out on their page indicating to me that they don't carry it.

Thank you

Reference the gm shop manuals in the forum, they’re a great reference for parts and installation instructions. Best regards
