67-69 Barracuda Dash for a 71 Duster?

I installed a complete 70 Duster into my 68 Barracuda with no issues.
While I was doing that, I also had a 67 and a 69, complete take-outs, to chose from. I noticed that every year has enough differences that I had to install completes.
Since I had a console column with no ig,sw, I had to cut a hole in my Duster dash for the 68 keysw ;no big deal.

BTW
This goes for the grills also, each year is subtly different. I managed to put a 69 into my 68 fenders, but it was an adventure.
