No they do not fit the G28 kits, but the fender openings can be modified to fit the lenses. On the G28, the left opening (drivers side) is closer to the OEM size than the right. To get them to fit properly, you will have to enlarge both openings, but on the passenger side you will also have to trim about a half inch off the side of the front hood (trunk), and then extend the fender mating line to the hood to match.
I made my buckets from OEM headlight buckets as well, and this is what I had to do to get them to fit.
