70 c20 wiring harness ?'s

[c20pickup]

looking to replace the complete wiring harness in my 70 chevy c20, have a couple questions.

what company offers the best kit? by best kit i mean most complete, junction box and all, ease of installation etc. i see lmc has a kit, american autowire, and painless

id like to keep most parts stock, but down the road i would like to add some more powerful headlights, an am/fm radio and maybe a few other things, but other than that she should be all stock

im basically clue less on wiring so any help or suggestions would be great

i do have the stock wiring harness and all, however its seen its better days and has been cut up over the years, so having a new kit would give me peace of mind

also, what would a nice kit cost me? i havent looked at to many kits but lmc's runs for about 700$
i also plan on running aftermarket gauges and gage cluster in the future
