I have basically the same car...base 350 horse GTO. When I went back with mine, I changed what I wanted to change as I'm not absolutely anal about original equipment...however, with every change from stock I made on my car, I tried to make it appear as if it COULD have been original.
To the unaccustomed eye, nothing looks out of place except the late style alternator. Been waiting for over 10 years for it to crap out so I can replace it..lol
Here's an example... a gutted voltage regulator in the stock location on the firewall to hide my modified 12 vdc buss bar. I never liked that big lug buried in the wiring harness in the original.
