The aft window is hard to get into place. I found a way to accomplish this with one person. I clecoed the aft to the turtle deck skins. I ran twine thru the top three aft rivet holes in the window and brought them forward of the rollbar. I tied all three together. I looped a ratchet type hold down thru the knotted twine and the bottom of the rollbar. I used the ratchet to pull the window forward unit it was in the proper position. I dirlled out several of the 40 holes in the front of the window and clecoed in place.
