I must've missed the original question (been having email troubles lately).
"Whitworth" bolts do indeed take special wrench sizes. There is a chart at
http://www.britishtool.com/socket.htm
that gives decimal sizes for BA, BSF, and BSW wrenches. Note the
interesting relationship between the BSF and BSW sizes.

Not many, but some. Here's a few that come to mind that need Whitworth
wrenches (although I believe they are actually BA threads) :
SU damper pistons
SU mixture adjustment
SU throttle shaft clamps
nuts on starter solenoid
nut on starter terminal
And a few more that are BA threads :
small gauge studs (I just checked this the other day, no they aren't that
weird metric size that others including me have said they are)
screws that hold vent door to body
screws that hold door strike plate to body
screws that hold soft top straps to body
screws that hold "toilet seat covers" to body
screws that hold trunk latch to body
I'm sure there are more, but there's a few anyway.
