Installed the Front Only kit on my '68 Cougar. Excellent quality and easy install, and clear instructions, and the NU-Crank switches don't change the look of the interior at all. The vendor offers a single master switch that you can wire in and hide away so you can use that switch to open the passenger side window from the drivers side if you want. WCC should look at carrying that option as well. They also offer regular 2+1 (master and single) switches if you don't like the NU-crank switches. All in all, the best mod yet for my kitty.
