Dear Hans;
Yes; use the 'adapter plate' for the water pump, with your 'old' dampner, so the pulleys/belt will match and look orginal.
The bell housing/flywheel/clutch will fit too and all the (clutch) linkage will be the same, as well.
An Alternator is only needed for AC.
You'll need the trottle linkage off a 57-58 (era) truck though.
Good luck.
