Quick tip. When installing the new covers, be sure you have enough foam in the front corners, [the older foam kinda sags there] or you will have a wrinkle there. Also, go all the way around the new cover with a FEW staples, and DON'T drive them all the way in. You will probably have to remove a few to adjust the tension on the cover and it is far easier to pull them out if they are not flush. It might take a few tries to get the fit perfect, but staples are cheap. Once you have the right fit, then staple it permanently.
