Making My Dads Dream a Reality

If you have upgraded all you say, then you are more interested in making the car a comfortable safe DRIVER than you are a restoration jewel. Good for you! IN that same spirit, I would recommend doing @crackedback's headlight harness upgrade and also adding these:

Hella 7

By adding those two things, you will actually be able to SEE and you will add relays that take the load off the headlight switch. I did it to my 64 Valiant and it is literally a night and day difference.

Good luck on your journey and my condolences on the loss of your father. What a great way to memorialize him!
