Not as good a fit as the original, but good enough.
I replaced the original lid which formed bubbles and rust after abou 6 months. The new lid fit as it should and was easy to install. However, in installing it and a new diffuser panel, I noticed the the arms on the bottom half of the Fuego grill body that support the diffuser panel and the grating are rusting badly, It seems that this should not be a problem after about 15 months of owership. While I am happy with how my grill works, I am disappointed about its durability.
