Built in USA

didnt know that , have been running purolater --

dont it piss u off , to buy a hotrod part from jegs , or summit , and it has metric bolts / nuts ??!!

It damn sure as hell does. I cannot STAND it. It reminds me of those late 70s/80s GM products. Their alternators had the top bolt that was 1/2" head and the bottom was a 15mm. That's but one small example.
