re-wiring a 69 Dart

On the purple car it's the factory harness. Just deleted the ampmeter.

The silver car had a painless harness in it. Never again...

as far as the tin work, no, but it's very self explanatory. The 69 insert is longer than the 73

I'm looking to rewire the whole car as well as add a custom dash and radio. I never though it would be so difficult.

Why never again on the painless kit? Did you use the one made for Mopar?
