Carter vs carter fuel pumps

One has to wonder, tho, in the current state of chineseoated parts, if any of this is any longer relevant? Can you actually BUY rebuild kits for carter pumps?

By the way, "one hell of a long time ago" I sold auto parts in a previous life. I don't remember selling ANY pump rebuild kits, although I may have sold one or two. This all started in about 1974
