Looks good! I think you are on the right path by working on the mechanical side of things first and getting it driving. After you drive it for a while, you will know what needs to be fixed and wont' have to worry so much about scratching the paint/bodywork. I wish I would have went that route with mine instead of tearing everything apart as soon I got the jeep and doing a frame off from that point. I am still finding little things that need to be fixed, but without the jeep running and driving I couldn't know before hand. Plus, I have to be VERY careful and not dent/scratch the amazing finish my body man did!
Keep it up!
