OK, that's an older form 337. Does it have anything written on the back?

Yes, form ACA-337 (4-52). On the back is block 8, description of work accomplished. It contains a weight and balance table and the text "Fabric removed and 020 metal installed"

Dan, Did you have a chance to look to see if the portion (about 3/8") of the tank cover that slides underneath the fuselage top skin is riveted to the butt rib on your plane?

Thanks,
Dave

Dave, my apologies. Forgot, then got busy, haven't been to the hangar in a while. Im trying to visualize what you are describing. Ive never had the tank cover off in the few years Ive owned it. Cover does slide under inboard panel but confirming whether it is then riveted to the rib I think would require some disassembly?

Does this image help? All PK screws securing the cover
