Yes, I had forgotten that those are machined as a pair. I'm sure many were mismatched.
When I was a kid my dad was a mechanic. He was also a machinist and was allowed to use the machine shop at a couple of the bigger parts houses in Amarillo. I often went with him. Those guys knew their stuff. When I was a counterman for several years I got to work with one of those old time lifelong parts guys. He taught me so much but there was more in his head than there was in the books.
