Wood insert for large fireplace

[R3a1e]

Hello!

I seem to be running into a roadblock when trying to find an insert that’ll fit our fireplace. Firebox opening is 38-7/8" tall by 42" wide. I can’t seem to find any units that come with flashing kits big enough to cover the opening. Does anyone know of any in particular instead of having to go the custom route? Thank you!

That's a big opening. I thought sure the one we used on our Century would be big enough but it's not, it's 32" x 50". Sorry.
