Shane, as you know, my GTM had been modified in some areas previous to my ownership so I cannot say definitively how it would fit a standard GTM, but for my install it happened with everything being under the dash and just mounting to the body. It mounts with a nut on the wiper shaft, and then a bolt in the body of the unit to resist torque. The unit I used does only have one speed, but multiple speed units are available. You can adjust the sweep angle, which I did, and I am using the 110 degree sweep. The only modifications I had to make was to cut out the sheet metal "box" that sealed the stock wiper mechanism from the hood area. I then just sheet metaled over the opening. I think you can see the one side of that sheet metal cover in this picture. Sorry I do not have a better picture and would take some for this thread but the car is in the trailer while I work out some construction issues around the shop.
