Title: Help Me Find Accessory Bracket Bushings
Post by: Dr_Snooz on January 28, 2025, 09:10:26 am: My '89 350 has these amazing cast aluminum accessory brackets.

The brackets use these spacers to align the pulleys.

One of my spacers has gone missing. I'm trying to find a new one, but don't know what to call it, or the GM part number. Nor am I having much luck searching the online parts catalogs. Nobody has any drawings or anything.

Can someone help me out here?

Technically it's a split flanged bushing. If you google it you will see them.

They're both trash, BTW. All pitted and nasty with rust. I would replace them, but they're expensive.

Post by: Dr_Snooz on February 04, 2025, 11:07:58 pm: I can't find these bushings anywhere. I'll just keep rocking the flat washers I substituted in there temporarily. Hope the tab doesn't break off.
