Welcome aboard Carlos! We have several members who own a Ghia, or have owned one in the past, so I'm sure that someone here can point you in the right direction with anything you need to do to your new (to you) VW.
As far as shops go, there aren't too many around that care to work on air-cooled VWs. One that does work on them is Jim Lockhart on Rossville Avenue. I can't "personally" recommend him because I've never had him work on any of my VWs, but he has been in business in the same location for many, many years and comes highly recommended by a lot of people.
The best VW mechanic I've ever met is a member of our club. David is his name, but he's know around here as "The Godfather." He uses the screen name "RetBugtech" and like his user name suggests, he's "retired." But every now and then you might be able to entice him into "laying hands" on your vehicle, and he's always willing to give you advice on how to correctly do it yourself . . . and he won't even throw rocks at you the first time you don't listen to him. He might the second time, so be careful. :lol:
