Yep, saw them this morning at Lowes. They had the chrome plated ones and black plastic spacers. They had the 1/2" for sure, not so sure about the 1 1/8" length but did have the 1" length. I made a back rest extension a few months ago and sprayed it with black Flex Seal. That stuff is hard to scrape off with a utility knife. You might give that stuff a try to make 'em black since they won't get any abuse under the rack.
