[Healeys] Crankshaft Nut

[Rick Swain]

Can anyone tell me offhand the size socket I'll need for the nut on the front
end of the crankshaft? The car is a 6 cylinder but I seem to recall the 4
cylinder one is the same. I have to tighten it and need to go to town to pick
up a socket. It looks to be somewhere between a 1 5/8" and 1 3/4" but I won't
know until I pull the radiator and can get a good measurement.
Thanks
