Brake Noob

I adjusted them.

I'm sure you did. My comment is about the hooks of the adjuster's overload spring facing out.

It's not tons of pressure to stop, just different going from 2017 and 2018 cars and their brakes to a 69

Yes it will feel different. Modulation is different too because of the self-energizing nature of these drum brakes. The driver is the ABS and drums are easy to lock up so the more you can get a feel for modulating them, the better.
Change the linings of either or both shoes and the feel and grip can change.
My suggestions about things to note were only so you can help yourself be a little more knowledgable about you have. That way if you change linings you have something factual to compare. The only other information you're going to typically get is whether its an organic, semi-metalic, or ceramic compound.
