Beats me.
I'm kinda tired and have a bad time today with long term memory but I went to a place in Chicago, that was supposed to have lots of parts for MG's and they didn't have anything... and thats when I gave up. thats before I had internet, like early 90's.. who knows maybe they have something now, really haven't searched for parts... I looked for pictures of "my" car and found a couple sites a few years ago.
