Painless wiring???
I did the Painless kit on my 1970 Duster and found it very friendly. They do not have wiring for the RallyDash but I sold the dash and it paid for the wiring kit and I made my own custom dash to my own taste. no matter what kit you ask about you will find someone who had a hard time with it. The painless kit marks all the wires and even though they didn't have a diagram I found it easy to understand what they sent with the kit. To me ,well worth the money. Complete job took a weekend.
