Can you delay the project while you search? My mcm was white marble Roman brick- luckily I found someone who was putting in French doors in a house with the same brick so they gave me their leftovers. When I was done with my project I gave my leftovers to someone else with the same brick. Alternatively can you harvest from somewhere else on the house? Or stucco in similar color...

I am waiting until spring, so I have some time. Good idea — and there are a few houses in my neighborhood with the same brick. I should reach out to them. I am outside of Detroit, so I am keeping an eye out for any demolitions of buildings with the same brick. Thank you!

Good luck! Hopefully you find that pack rat neighbor who has a stack hidden in their yard.

This is always an issue , could you show the rest of the house exterior to maybe see a spot where you could replace brick with siding and still have it look good.
