The AAW is better then the Painless.I think what you are talking about is a classic update kit. I thought about that kit as well, but it is not much different from a Painless kit. That kit has the new style push in fuses, extra wires for fuelpump or power windowes and many other things as well. That kit is also trim to fit, not direct fit. I feel that it is not out of the question to start on Friday after work and be driving your car before Monday with the plug and play kit with no problems. I replaced my entire 69 harness in a day. The 67 has less under the dash and should be quicker. The classic kit is just as much of a pain as the Painless kit. I know the plug and play kit is more money, but it is a one time job, and should last as long as the original one. Good luck and hope this helps.
