I had the same little fitment issues as you, but not nearly as bad. Ditto on drilling the control holes out a little bigger, as you need the stock covers from you old mirrors. I went one step further, stop by your local fabric place or whatever, pick up a 25 cent sheet of black felt, cut 2 circles about 1 1/2 inches round out of it. Cut a small slot in the middle, slide them over the mirror control rods, and put your covers back on. Gives a nice finished look and covers up anything you might see beyond the hole that you drilled.
