Steering Cylinder Tiller Arm Bushing Source?

[rustybucket]

Replacing my Hynautic k31 steering cylinder with a new seastar unit. The bushings that attach the cylinder to the tiller arm have seen better days and I want to replace them while I've got everything apart.
They appear to be copper or brass/bronze maybe? Anyone have a source for these bushings? Looks like the ID is 1/2"-ish and the OD is 3/4"-ish. Being that they are worn I'm not 100% confident in my measurements.
Any guidance is greatly appreciated.

Usally made of Silacone Bronze. For quick results, I stop my hydrolluc shop. You also can tap on Sam's, McMaster-Car or other shops but at a counter with hardware in hand is hard to beat.
