Can anyone tell me where the stringers attach at the rear? Per the fuselage assembly drawing the stringers run all the way back to the same station as the stabilizer jackscrew but there are no attach points in that area. The old stringers have holes drilled in both ends, FWD ends have two holes that match the two holes in the attaching U-channel, the aft ends have a single hole that matches up to nothing. Am I missing some attach points? I just purchased the PA-22/20, S/N 22-4725 as a project I'm trying to see what I have and what I need. It's been through 4 or 5 owners now as a project and has parts of two airplanes. The stringers also appear to be the wrong profile per the same fuselage drawing Fig 4. It's like a giant jigsaw puzzle with missing and extra pieces.
