66 Barracuda 273 Intake Manifold options?

Hello dudes!
I am having a hard time finding a replacement intake manifold for our 66 Barracuda.

273 2bbl.

I saw a couple threads mentioning a few including the Edelbrock LD4B manifold, but that doesnt appear to be a direct swap. I like the thought of upgrading, but were are trying to remedy a thermostat flange leak.

Thank you all
