The '57 thru '59 Y-block car distributor is a direct bolt-in, but they do not have the tach cable hookup on them.
'57 and later used different points, condenser, rotor and distributor cap than the earlier distributors, so you will need to get those also.
Pertronix makes an electronic kit to replace points and condenser but I don't recommend those.
I suggest, if you can find an old used '57 & later Y-block distributor, rebuild it yourself with new shaft bushings available at some of the resto parts suppliers rather than sending it off to rebuild. I have heard stories that the rebuilder (Cardone, I think it was) is messing these up somehow.
The Ford car shop manual gives important tolerances to observe if bushings need to be replaced.
Don't forget to lube that shaft at the fitting on the side of the dizzy housing.
