Mike, as I said, my bar is a 199 and it is 1 1/8”. I bought it quite a while ago. I would
assume that Addco changed it at some point. Perhaps call the company I added a link for that lists it as 1 1/8”. They may have “old stock” as I doubt they’re a big selling item.
BTW, I did not buy mine from RARE. I can look for my receipt but I don’t think it matters at this point.
Update! I rechecked that link I posted earlier and it has changed to listing it as .875!
Good luck . . . .
