Radius arm bracket internal diameter

[CabinCruiser]

The "donuts" on my radius arm brackets appear pretty chewed up with rust. I'd like to repair them without replacing the entire bracket. I'm looking for the internal diameter of that hole?
Thanks

The hole itself is 1-3/8" in diameter. Mine has a a radius on the leading edge of the hole of 3/16", but I am not sure whether that is typical or not. My brackets look really good...

It's about the same size as that step of the new bushings.

I thought someone was selling just the donut that you can weld on to a good bracket.
Seems like a bit of work to grind off the old one and weld on a new one, but perhaps less expensive and less intrusive a job than replacing the whole thing.

I could be mistaken but I thought I remembered seeing them at some point. Just looked on our site (just in case it was us!) and even checked out Graveyard because they have lots of little rust-repair bits right up this alley. But I did not find them.
You planning to just dress yours up a bit by grinding off the rust? Or do you think they need a real refurb with new material added?

Well I’m in the fabrication stage of a frame-off build. These just looked chewed up to me but the brackets looked fine. Figured this was the best time to deal with it. I thought if I found the correct size washer I could just grind these off and weld a few stacked washers in there. Maybe these aren’t in bad enough shape to even bother?

I would definitely repair that since it will chew up the bushing.

...weld a few stacked washers in there.

Bad idea. The sharp edge of the top washer would cut the bushing. The original donut had a rounded inner front edge, to match the contour of the bushing.

Thanks for the feedback. I usually gravitate to JBG due to location but it seems like the ones from WH specifically reference the leading edge of the bevel and how it relates to the bushings. I’m guessing they (first image) would be preferred to the JBG option (2nd image)

Everything about the top image looks significantly better; not just the weld quality, but the placement, too.
