These are my 66 and 67.
The 67 is better since it has the factory 12 volt system, ball-joint front end, and sun roof. plus the dual-brake master cylinder, and collapsible steering column.
The 66 is not in very good shape,. I need to sell it. It does have popout rear windows which are nice.
The 67 starts and runs, but needs some TLC. It is pretty much original, with a 1300 cc engine. I have the emblem from the rear cover, didn't want it to fall off.
I think the 67 only has perhaps 40K miles on it.
I wouldn't mind making a baja bug, sure would be a lot easier to pull the engine, but can't bring myself to get out the saw.
