It shouldn't be very difficult to adapt the cable to the existing SU
linkage. Those SUs originally were actuated via a "bar" linkage that
pushed up from below. You just need something to steady the cable
(scavenge from current Stromberg setup) and a way to attach the cable to
the linkage on the carbs. At worst, I'd think you could probably order it
through Rimmer Bros., since this essentially would have been the home
market Mk.IV specfication (I think).

For what, sentimental reasons? ;-) Note that the improvement will NOT be
exponential. You might even lose a bit of response at lower rpm's, but
overall you should see maybe a 10% or so increase in power. Of course,
going from 48 to 42.8 hp isn't too impressive when you look at it that
way, but I suspect you'll feel the difference nonetheless.

Amen to that!
