I just purchased a '71 Cutlass convertible which is in very good shape. While the body restoration got good attention and it has a new top, but all the weatherstriping is dry rotted as well as the well liner. I am mechanically inclined had have done some interior work on a TR6. How difficult are the following jobs or should I hire a trim shop?<BR>1) Installing new pads for the convertible top<BR>2) Installing a well liner<BR>3) Installing all new weatherstriping (top, windows, doors, hood, trunk, etc)
