Mine had scuff plates (angle bar) bolted to the chassis. I now have roller stops from Melyvn Rutter.
Same here. It's never been an issue in the last 15 years, either from a driving point of view or MOTs, where every tester I've used knows about the exemption for Morgans.
It's certainly worth getting your dealer to have a look at, but I wouldn't be in the least surprised if you get the 'This is normal for Morgans, they all do that' response.
