After market wire harnesses

ok guys, need some input here. I am to the point of my build where i just need to wire it up and then its off to the races.

here is what i do and dont have on my 1967 dart.

big block with factory style alternator. (externally regulated?)
MSD ignition (6al box, msd billet distributor, msd blaster2 coil)
no wipers
no heater
no radio
have autometer guages in the dash (all mechanical gauges, except volt and fuel level)
67 floor shift steering column.

I want to keep the original keyed ignition switch in the dash (even if i have to cut and splice the original plug into the new harness)

dont mind running an aftermarket or other manufacture wiper switch.

I am a complete novice when it comes to wiring. I have done several car stereo installs and have done electronic ignition swaps before but that is about the extent of it. I have a good set of tools and know how to use them. This project has got me rather intimidated.

I have been looking into the universal kits that would be used for street rods. I like the Ron Francis "bare bonz" kit. has 10 circuits and 8 fuses. keep reading bad stuff about painless and how not "painless" it is. Get paid next week and am making a decision then.

ALL INPUT IS GREATLY APPRECIATED! what do you guys recommend?
