Rebuilt Alternator ???

Picked up this rebuilt Alternator. Looks like one of the grounds was bent in shipping. I noticed my other Alternator does not have the extra ground. I know grounding is a good thing, but do I really need the one that's bent over in the picture?
Second, take a look at the spacer. It's not really correct, and has the belts not lining up just right. How can I get that spacer out? Does it have to be pressed out, or can I knock it out with a hammer and punch or dowel? Thanks for any help

Remove the bolt and yes, you can hammer the spacer out, if it does not come out by hand
