Can’t comment on the 71 but used a Dakota Digital in my 69 Super Beez. Easy install looked great in the car and worked flawlessly. I have used Dakota Digital on several builds and have never had an issue. My 55 Dodge pickup has a Dakota Digital in it. That install was in 2013 and has over 65,000 miles on it. Never had a problem. Go for it you won’t be disappointed.
