No diesel G was ever marketed to the U.S. However, many were imported on the gray market. I have seen a lot of 617-powered five-door (long wheel base) G's pop up on eBay and craigslist. I don't know the dates off the top of my head, but most seem to be from the early to mid 80s. I believe importation rules changed in the late-90s making it pretty much impossible to import a car. There used to be a place in Calif., though, that would import and adjust Gs to meet U.S. emissions. I can't remember what they were called, and I'm not sure if they still exist, but most of their Gs were expensive.
