I had a run of cars that only needed one or two things. like get the engine running and paint it. or put an engine in and drive it. This one is a different beast and thats why the comment of "dont take a car completely apart struck home for me. Sure, I didnt take it apart, but I took it on in its "boxed up" state. It was missing all sorts of parts that since I had never done an A body....well I would have been lost without FABO. So my question is.......for those that have undertaken a complete "take it apart" scenario, have you gotten it back together? I have a feeling that there are not that many out there. Especially if you are doing all the work. Sans Machine work.
