I would think that a universal kit would work pretty well for our trucks - especially 67-68 models. The wiring is pretty simple compared to a car - especially a newer model.
If you were careful, you could run all the wires and bundle them together and then just wrap any exposed wires for protection and to give it the 'factory' look.
Would you trust a 30 yr old tire? why trust 30 yr old wires?
A complete re-wiring is definitely high on my list. And I'd like it to be nice and compact, like the newer vehicles. Plus think of the benefits of modern technology - you could run a kickin stereo and all the lights you wanted. Plus - you're gonna get a one-wire 100 amp alt. to go with it!!
and then there's a/c - and then the power windows and door locks, with keyless entry for the shaved door handles!! :twisted:
sorry - got a little carried away.
