I have a BJ8 made in 1966 (a later s/n after 26704), a few years ago when I bought new wire wheels for it, I decided the old knock offs were just too beat up and didn't look good enough for the new wheels. So I ordered an new set of knock off from Moss. Being the later BJ8, I ordered the 8 TPI versions. While installing them, I noticed that my left rear hub had 12 TPI threads. I assumed that the hub had been changed along the way prior to my ownership. So after some consideration as to just have Moss exchange the new 8 TPI left rear knock with a 12 TPI one, I decided to buy a whole new hub with the 8 TPI, for consistency.
My friend Jim was over last night with his BJ8 ( also after 26704), we were cleaning up his wheels and when I was replacing his left rear I noticed that his left rear also had a 12 TPI hub, with the rest being 8TPI. My first thought was, " Huh, what a strange coincidence, both of these cars had a damaged left rear hub in the past and the only replacement hub was an older style 12 TPI version?". Or is there something else going on here?
So, which is it;

So, which is it;
- Were the left rear hubs in the 8 TPI cars purposely made to be a 12 TPI hub?
- Did the factory run short of 8TPi left rear hubs and just installed what they had lying around?
- Is the left rear hub more prone to damage/problems causing their replacement more often? And the 12TPI versions were more plentiful as replacements?
- Just coincidence?
