I think they were to mount some clamps that hold the battery wire to the starter. I saw them in some parts catalogue at one point. Found some here.

I thought the PO had added mine and I wasn't sure they were supposed to be there, but I guess they are. The PO used a different clamp that has the improved benefit of removing skin from knuckles and inducing a torrent of cuss words. I wish I knew these existed like 2 months ago when I replaced my starter.
