OK, that would be a Deluxe Station Wagon - curved rear glass, eyebrow windows, and sunroof. Station Wagon (which I had for a personal ride) had curved rear windows, but no eyebrows and no sunroof. Kombi (which I also had one of at one point) had only flat glass, the rear quarters were sheet metal.
That's a nice example, most of them - mine included - succumbed to rust. The engine upgrade was a fairly common bolt - in, as was the conversion to a one piece transaxle case with synchro on all four forward gears. Bug components bolted right in, you needed only to swap the distributor and axles; and flip the ring gear over to the opposite side of the case. Faulire to flip resulted in a four - speed reverse and one very slow forward.
The one pictured dioes not have the proper distributor, it has a Beetle distributor. This will eventually lead to engine problems, although with only 22K on it it probably isn't apparent.
