I have a nice 4.10 from a 325ix. It has 146K on it and locks up nice. As you can see from the pictures, it is a clean unit. I didn't paint it, just sprayed some degreaser and hosed it off. One of the fins is cracked but this wont be a problem and you could just toss on the cover from the diff you are pulling.
