Hello TR3 Aficionados--I have read all the threads (discussions) about Whitworth threads (fasteners) which are really interesting and on point but not quite what I am looking for. I have made a complete restoration of my TR3A (TS50260L) and over the years have always replaced a lost or missing nut, bolt or cap screw with a UNF (SAE) part that seemed to fit. The only exception I found was the mixture adjusting nut on the SU carburetor. I am just wondering if anyone has ever seen an inventory of where Whitworth threads were used. I used to think all post WWII cars exported from England to the US used UNF or UNC (SAE) hardware. After reading the threads it appears there were several exceptions.
Thanks for your interest,
