NE1 install Elec life PW kit in a 70-72 Duster??

I'm looking at the Electric Life power window kit for my Duster. The problem is that it lists them for 73-76 and theres no picture to compare regulators. I know they changed things in the doors from 73 on up, possibly the regulators? Has anybody used this kit in a 70-72 Duster or Demon? I really liked the kit I had in my 69 RR.
