I saw some for sale at the mjcq swap a few years back (2?). They had holes and were original- no vehicle to date from sorry as they were loose.
I didn't get them as I didn't think I needed them at the time... Wish I had as I found out the ones I had turned out to be repro!
There was some old threads on the G about it. I think frank berg was talking about it? I can't search at the moment sorry.
