Lindy, Every set I have seen has 2 crimped "riveted" nubs in the three places they are attached to the frame, and only one is used from the factory. Which makes reassembly easier! But starting with a set that has minor to no pitting is better in the long run. These are pretty common swap meet items. I will PM you if I have any extras. I know I went through a few sets to get one good set.

There was a post on here a few years ago that had detailed pictures of this being done. I might have it saved.
