These are pictures of the rain gutter on a build jig, leaned against the wall. I need to make a longer roof, but had a decent donor front and rear piece so those are tacked on.
I believe the material was 12 gauge but it’s measuring a little thinner than that. 1x2 1/2 tube. We split the tube with a jigsaw, if you look at OEM one side is taller than the other and we tried to split it accordingly.

ETA I will say that the 1” width plus the jigsaw kerf left very little room for error, and we’re not perfectly straight to begin with. You might consider 1 1/2” if your going to death wheel it or have some other method.
