Everytime I send something out to be restored, I take a LOT of pictures. Reason is just to make sure I get my original parts back but the part numbers, date codes, condition, etc is the same. On the restorers end, I'd want him/her to do the same when it is received. Then discuss and mutually agree what is to be done. Restorers should take pictures of the final product before being shipped back to the owner. Any questions or discrepancies on either end can be ironed out then. Like mattsMopars said COMMUNICATION is key. I don't know if it was done in this case, probably not enough, just saying.

BTW- The first pictures posted of the motor, unacceptable to me. No, not trying to bash anyone
