An alternator is best ask for one from a 1989 Camaro with V-6 engine , it will be internally regulated . you'll need to either buy a fancy-schmancy alternator bracket ($$!) or reverse your old generator bracket 180° and drill one hole in it so it holds the alternator in correct alignment with the pulleys . you'll need some pipe or a stack of flat washers to shim it a little bit , I used one long bolt instead of two .
but you can also use a 12 volt generator and regulator from a 1959 Chevy pickup .
A 12 volt coil , ask for one for a 1972 VW Beetle .
A voltage dropper for the fuel gauge .
new headlight bulbs , # 6014
Taillight bulbs # 1157
Parkilight bulbs , P/N depends on how many contacts they have .
Flasher for the turn signals , again , P/N depends on two or three wires ti it .
Battery , a BCI group 26 size will fit under the floor in the original battery box .
you DO NOT need to change the starter ! the original starter will work just fine on 12 volts .
I hope this helps , I and other have written this up before so look in the archives for more detailed info .
