If I was going to replace my harness I would use American Autowire Classic Update. I had the 18 circuit Painless harness around 17 years ago and it was a pain to install. The fuse panel is larger than the original so you have to drill new holes. I don't know about now but back then there were too many wires that I had to terminate.
Is your car all stock or modified? With the 67 and the AAW classic update harness you will have to enlarge the fuse opening slightly. Even so, I installed one of the AAW CU kits last year and love it. It will take longer to install but you have so much flexibility with it. Be sure to either buy or rent the crimpers (a must). I bought a used set off of Ebay for half the price to rent them. The AAW kit comes with EVERYTHING, I believe the painless one requires you to re-use some old connectors. AAW tech help is outstanding!
Yeah the Factory Fit line is the best OEM style replacement out there. Plug and play 99% of the time, and their customer service is top shelf. And as stated if your looking to update to blade fuse the Classic Update line is great. And if you have a resto-mod and want a custom call and order what you need and want.
