IT'S NOT METRIC.... Metric was not used in the UK pre 1973. There are only 2 possibilities, either it's UNF (SAE) or it's BSF (British standard) fine. I have several here, so I'll measure one and get back to you....Can anyone tell me the size of the metric hex jam nut that fits on the mounting stem of this reversing lamp? No one who I have taken it to has the answer. The picture below shows the stem I'm talking about. Thanks for any help!
