A question about assessing a ramp queen for purchase (disassembly of the wings...)

[geosnooker2000]

I spy, with my little eye... a 1969 Cherokee 140 that looks like it hasn't been flown in years. This is at a local GA airport. I think I see (from the closest I can get to it) a broken-out passenger door window, the paint looks BAD... really bad, and even a baseball-sized hole in the pilot's window (although that could be just a vent hole that has lost its fitting). The front tire is flat. The spinner is missing.
Anyway, I am considering buying it as a project, but I would like to know the condition of the main spar connection bolt holes. Did that proposed AD get passed on the PA-28/32 wings? I can't find it on line. All I can find are articles about a "proposed" AD. I am in the middle of getting in touch with the owner to see if he is interested in selling. Since I have gathered that just removing the wings to inspect could cost up to $3000, I was wondering if it would be LEGAL... for me to disassemble the wings from the fuselage, as if I was going to transport the plane to a hanger by trailer (because really, I probably would do that in the first place if I bought it), and then have an A/P inspect the holes, and if no defects were found, supervise me reassembling the wings to the fuselage? IOW, is it all about the re-attachment, or BOTH the detachment AND re-attachment?
