Michigan 75iii bucket pins

Hi - I'm looking for the boom and pushrod pins and bushings to connect the bucket to the loader.

The boom to bucket pins are about 2.25" diameter x 6" long, and bushings are about 2.75" o.d. x 2.25" i.d.

The pushrod pins are 1.5" diameter x 10" long.

Are pin/bushing parts from other machines able to match?

Thank you!
