American Autowire or Ron Francis?

I am getting quite fed up with 49 year old wiring. Intermittent tail lights, dim headlamps, very dim dash lights, intermittent courtesy lights, fuse block getting HOT, et cetera. I have to wiggle the fuse block wiring to get my tail lamps to function. This **** is NOT COOL! When I run my heater/defroster, that wiring gets VERY un-cool!

I have crackedback's headlight relay kit on my wishlist, and I already have slantsixdan's turnsignal/brakelight part.

Who here has used any of the following, and what were your thoughts. I need to hear the good and the bad and the why of it. Also, what special things did you need to do to get the general wiring kits to work on Ma Mopar's electrical system?

American Autowire 510603 1967-1975 Mopar A-Body Classic Update Kit
American Autowire 500695 Highway 22
American Autowire 500703 Highway 15
Ron Francis XP-777 61-75 Mopar Express
Ron Francis WR-95 Retro Series
Ron Francis AC-68 Mopar Access 24/7

I am leaning towards either 510603 or XP-777 right now. I will be calling both next week on my lunch break.

And one for the My Luck thread. ;)
