I'm not aware of any Whitworth threads installed by S-T (at least on a
sidescreen car). There may be some Whitworth and BA threads on bought-in
components, like SU carbs, Smiths, and possibly some Lucas. But I'll be
shocked sh*tless to learn legit Withworth threads were used in a S-T engine=
.
Jonmac, I'd never heard that metric and inch fasteners were used on the
line at the same time depending on the end market for the vehicle. That's
a fascinating bit of trivia, and one of the reasons we love having you
here! What time period are you talking about for that? Maybe 1970s?
