Anybody know the actual toyo number on the 86/87 swing arm bearing?

The bearing dimensions are 20x26x30.  I just usually type in the bearing dimensions and bearing type to get the part number or at least the bearing manufactures catalog page.  In this case it’s a drawn cup needle bearing.  I’ll see what I come up with.

Great information. I already bought a rebuild kit with needle bearings in it. I need to speak up for better advice before buying stuff. I got so much I want to do to this quad. Powder coat (no idea ) need a exhaust clamp for a PT and fat boy, when you buy aftermarket a -arms do they come with bushings? Looking for rebuild kits for master cylinder and all 3 calibers. Got a long way to go. Slowly but surely new parts are starting to pile up.

Aftermarket a-arms will be ready to bolt on if you buy them new... I've rebuilt 2 complete sets of brakes using Shindy rebuild kits & have no complaints, there high quality parts. If you need a rear mc push-rod Suzuki part number 69670-00A00.

Any idea where this goes? I can’t find a home for it. It wasn’t on or bolted to the quad when I got it.
