Help Me Find Accessory Bracket Bushings
« 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?

Hmm, I am not sure where you would acquire that.  I would possibly start with the local Dealership to see if they can identify if it was available.

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

Look, they match now. Good grief.



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

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.

My dimensions are 0.515" D x 0.549" OD x 0.425" ID x 0.106" shoulder thickness. I should just design one with OnShape and have them made.
