If fitting the stand from scratch, it's easier to fit the spring to the stand, hook the spring into the frame, then lever the stand roughly into position, working single handed a short length of wooden batten avoids paint damage. Get a couple of temporary pivots in place, then replace one by one with the proper ones. Easier with the stand in the up position, better still with an assistant to offer support and a sounding board for the inevitable curses, and maybe a drive to the ER.
My parts book does not show a nut and bolt on the stand to retain the spring loop on the stand tag but it is the simple and obvious way to keep the spring in place on the tag.
