Took about 15 min with help from my wife to install. 3 screws in front above door released top to raise up, while she help top up, I removed 4 screws to release the mounts holding the elements and laid them down on top of oven insulation, removed top by pulling forward and lifting off range. Remove the tabs at back of old top and mounted to new top, removed the mounting strip on front of old top and mounted on new top. Placed top back on range and inserted tabs back into mounting holes and wife held top in place while I mounted the elements back up to new top with 4 screws. Lowered top back in place and replaced 3 screws in front.
