I have two broken rear mech a rx100 and a deore xt 750. They are broken in different places the Rx at the top jockey wheel and the xt at the main mounting boss can I take the two apart and make one good one do you think?

I really have no idea, but why not try to match up the parts, it will be interesting to see if it works.
