back for stove top

[My3buicks]

Does anyone know where I can find the hinged folding cover for the burners - mine is missing - I miss the extra top space it would make, but even more, I miss the backsplash it makes for grease.   - I saw a couple new ones on line(Atwood), but they are not a good fit.  My PU is a 78 Coleman with 2 burners.  Thanks
