489 Crush sleeve or Eliminator

I'm probably going to get new stuffs for my 489 as I don't know the condition of it. I made the mistake of putting the swap meet 741 that "worked good when he took it out". I put it in and it definitely did not "work good". Lesson learned, but I have a hard head.
Asking for a friend...is it feasible to change the ring and pinion using the old parts including old crush sleeve?
I would put the marking compound and check the condition before hand.
