Wiper drive arm

On my '70, the wiper transmission arm bushing that attaches to motor arm is broken. Does anyone know if the attachment end or the bushing is replaceable? Seems you need to buy entire arm assemblies, but my arms and pivots are in excellent shape…seems a waste to replace whole thing…any ideas?

Don would be the best person to respond on this one, but if he doesn’t have a good replacement, I would take the dimensions to my local bearing supply store and see what you can get.
Might be a little fun to press out the old one though.

Actually I will buy set from Don if I cannot find bushing…seems a waste. Thanks for reply…
