Got new black granite countertops and the cooktop looked old and dated with the element cartridge on one side and the griddle on the other side

Removed the griddle and cleaned underneath. Replaced it with the new cartridge. Removed the otherside (old coil cartridge), cleaned underneath and replaced it with the new cartridge. My stove now blends beautifully with my new countertops without having to replace my whole slide in downdraft Jenn-Aire range! Saved my about $2000!
