Welcome to the F1 Forum.
However, is this not an odd topic for a post. I assume there is a slew of components that will remain unchanged in the 2021 to 2022 transition. I believe there are major ones (such as the homologated Halo structure) and minor ones (such as the camera mount/footprint) remain unchanged.
Wouldn't this be more of a point of discussion on the things that are changing vs. those that remain the same?
