Hi kevkon, I have had the pertronix ignition for over a year and it works great and looks stock b/c it is hidden inside of the distributor. I have even had my heater control valve explode and dump coolant all over the distributor and it did not short out. The ac delco alternator is also awesome and has been one of the best mods I have done. I have a website that helped me with the new wiring harness (becareful I am not sure of your polarity so you might need to change some connections in your voltage box(it's the back lucas thing on your firewall)).
The Canyon Product 2 I had to fabricate a mount for it I used a 41/2inch 5/16th bolt grade 8. The pulley was different so I needed to get a new fan belt. I now have a dayco top cog 15405, it is narrower but works well. The alternator was from a 1970's camero I believe part number 7127103. I would love a fairey overdrive, use to have one on my old rover, they are awesome. Good luck, I hope some of this was helpful.
