I agree with Gee_Emm... cutting the vents is much easier than replacing the dash. The side vents are actually a circle, projected on the dash. I used a can that was roughly the same diameter as the dash vent and held it up to the dash and then ran a pencil around it to get the shape. I measured the distance up from the bottom of the vent housing to get the top and bottom of the circle and free-formed it from there. I used a body saw and it worked great.. no problem turning the circle. Just remember you can always cut or die-grind more metal out. Get it close and then fit the vent in place and it's real easy from there. Once I had the one side done, I used the "garage-hands" approach to transfer it to the other side.
