According to the Standard Triumph Hardware catalog, HB0968 is 3/8 UNC (16
tpi) 2-1/4" long.
TRF has them listed under HB968, $.80/each.

Odds are very good that your local hardware store will not have the 1/4"
increments in length. Although it's not hard to cut down a longer bolt if
you have the tools, I'd suggest just buying from TRF. Grade 8 will work
just fine (but is more of a pain to cut threads if you try to cut down a
longer bolt). Of course, it's possible the hole is deep enough to take a
2-1/2" bolt, but I'd measure very carefully before making such a
substitution. The holes aren't always tapped to the bottom, and the last
thing you want is a bolt that bottoms in the hole instead of clamping the
housing properly.
Don't forget the anti-seize and new lockwashers when you put it back
together.
