I found one on ebay, cost about 5 USD.  Search for micro USB jack.

Did I miss something? The title implies showing how to REPLACE the port. It ends with remove port and set aside, then reverse. On the off-chance the authors are still reading the comments, sarcastic “good job”. I also marvel that it took three of you geniuses to come up with this. I’m gonna follow Heliophile’s advice and search ebay, his or her 2 line comment was way more useful then the entire piece. Thanks Heliophile.
