Find a used 40" frigidaire...other than that, no one makes that size. Or reconfigure your cabinets and countertops for a 30" or 36" range....or have gaps until you can afford to remodel the entire kitchen.

Summit 40" range

Oops sorry it says it's 36". Look for a used Frigidaire 40"

It may be an option to use a 36" induction range and move the counter and cabinet down to fill the gap.
