Review on 18mm Bolt-Style Top Dead 🔧 Center Stop by COMP Cams 4792 by Scott Goff

I bought the 18mm by mistake, I found the 14mm locally, it seemed to work, I used it on the BBC, spark plugs 'flat' in this one Motor compared to a high angle motor so the stopper doesn't screw all the way in and touch the piston, but I took a chunk of the entire thread and it worked fine. maybe 2 full turns but not sure if that matters, that part was still a good start for not doing it yourself.
