Gentlemen;
Patrick's has the brackets for
using an Alternator in place of
a Generator.
Remember; you don't need an Alt.
unless your running A/C or a lot
of lighting etc.
A 1955-60 Generator is 12V & the
Regulator is all the same as the
6V (orginal) units in size and
look etc.
You can 'push start' too and @ 12
volts the current is half as well.
Good luck.
