On Plunger bikes the top of the stand flats where they meet the underside of the footrest forging in the down position suffer wear as does the flat face of the forging. This results in the stand feet ending up too far forward and the frame sitting just that bit lower when parked. Cue for a hernia as the bike needs to be lifted up and over to get it off the stand.
Rectification is far easier with a bare frame, so I'd say that the first stage of any major rebuild is attention to the stand, pivots and the forging.
Easier to fit the spring and pull on the stand, then use thin bar through the pivot holes to keep it roughly in place while you wiggle the pivot holes into line one by one and insert the pivot pins. Original pins had a grease nipple, threaded end and castellated retaining nut, washer, split pin. Plain bar, washers and a couple of split pins for each will do for now if you have no serviceable originals.
