Bob, as a point of reference, for whatever it's worth, I checked an original
1972 Spitfire MkIV currently in my care (and for sale, but that's another
story). I didn't actually measure anything, but it would appear that the crank
and
alternator pulleys are in line, and the water pump pulley "might" be about
1/8" closer to the engine. I know the crank pulley is original, although it
has
been off at least once for an oil seal replacement. I think the alternator al
so is original, but I'm not sure. I do remember putting a new water pump on
this car some years ago -- probably the ubitquitous Q-H replacement pump.
The misalignment on this car does NOT seem to be enough to cause any problems
with the drive belt itself, as there don't seem to be any wear or "stress"
marks.
