After thinking about this overnight, it seems I remember running into this years ago. I know several times at the salvage scrounging for Rallyes I have had to go through a bunch to get 4 to match. Normally it's width, but ocassionally I would see slight differences, even offset. I'm sure over the years Chevrolet has had multiple suppliers for these wheels. Also There was the GMC and the Chevrolet line.
