Well there are a couple of issues here......getting some young "buckaroo" in the parts department is almost always a bad sign.....see if you can find a "gray hair" that knows the old stuff.
Better yet is to do your own part number search and go shopping with the numbers. If you need a parts diagram for the idler I can post. Many of the idler parts were used for later models and are still available but there may be some that aren't.
You may also have worn internal bushings along with the external visible stuff.
Nothing that can't be fixed with some new, fabricated or good used parts.
Maybe someone local to you can put you in contact with a veteran parts man, they are worth their weight in gold and I consider myself lucky to have two such sources near me.
