I'm no pro mechanic either. I just had a couple daughters who wanted a Jeep and thought the project sounded fun. It never started out as a full body off rebuild, but if the family supports the project, you have a place to work (with a heater now!) and you are patient, it can be fun. I learned how to weld, the kids learned how to use paint guns, tools, etc. My 16 year old is driving to school now in a vehicle as old as her, that she built, and paid 1/4 of the bills for (I paid 1/2 they split the other half). She also is probably one of only a handful of students who can drive stick shift too! Any questions you have as you go give me a shout maybe I can help.
It was very easy the way we did it. We unhooked every vacuum line, hose, wire, etc (even the whole fuse box) and laid them over the engine. We removed the old tub before removing the power train and installed the power train before the new tub. I would have spent a little more time on the engine while it was out. I would have liked to have sanded the oil pan and painted it (rust will eventually eat at it if it isn't addressed) and we should have replaced the studs on the exhause manifold while it was out. Now I'll have to get a right angle drill in there to remove the studs as the exhaust is leaking a little. I thought about doing a clutch while it was out of the frame, but there was no indication it was on its way out and I figured I had 2 teenaged drivers who had never driven stick and would be learning so they might as well beat on the old clutch. They've done great and the clutch still seems fine.
Feel free to contact me again with any questions that arise.
