'67 Barracuda Aftermarket Wire Harness, Gauges and Classic Dash

After chasing my tail the for the last couple weeks I've decided its time to replace the 50+ year old wiring and gauges in the barracuda. Fuse box is corroded, wire is brittle in places and not much of it works. What does work is ignition, head/tail lights, fan and horn.
Have been doing quite a bit of reading about various brands like painless, Ron Francis and American Wire. Pricing on these kits seems to be all over the map from 300-400(RF and Painless) to 1000 for American wire.

Looking for opinions on which kit might better suite my needs based on the following:

• Using mopar electronic ignition
• Using Denso toyota alternator Denso 60 amp kit, small blocks | AR Engineering
• I would like to install a classic dash along with Autometer gauges. 1967-69 Plymouth Barracuda / 1970-71 MOPAR A-Body Rallye Dash Panel - Classic Dash
• Need a wire diagram for Year One turn signal switch, the colors are different.
• Dash mounted ignition switch.
• bypass the amp meter
• I wouldn't mind getting rid of the bulk head terminal at the firewall, its in rough shape anyway.
• concerned about how to tie into the factory switches like headlight, hazard, column, fan motor and etc.

If you guys have any insight or have done a wiring job please chime in. Also, if there's anybody in Boise, Idaho with experience even better...

Thanks in advance
Jim
