My old bracket was bent, so I sourced a NOS replacement, not realizing that the rubber bushings were a separate part.  My old ones seem welded in, but I've only tried impact with a socket, so far.  I did put the bracket in the fridge for a while, thinking the cold might shrink them a little - no dice.
Does anyone know any tricks to get these out?  Or have a couple to sell?
Thanks!

 Number 14 is what I’m talking about…

You know what bike you're working on, we don't. Always helpful to list the year and model.

You can try Yamaha or searching ebay with the part number if you haven't already... I got some a few years ago for a CT1 on ebay without too much trouble.... but I think I ended up buying a used bracket with bushings installed because they were too hard to change.

Thanks Mark, and sorry, I have a 73 DT3 250. There doesn’t seem to be any bushings for sale anywhere. I guess with how hard they are to get in/out, I’m a little surprised the brackets don’t come with them in. Oh well, live and learn…

Yes unfortunately that's why I've stayed away from NOS due to those bushings. There are usually ample used brackets on EBay and those bushings are usually fine.
