I have a set of the STI engine mounts I was going to put on my Gen 1, but ended up returning to stock before I did for trade-in. Looking at the parts diagram Gen 1 and 2 have different part numbers (41020CC000 [2022] vs 41022CA000 [2017]). The prior Gen mounts also have locator block on the rear bolt where as, at least in the diagram, the Gen 2 mounts do not. *Edit: The Gen 1 STI mounts also have this block
If I have time this weekend, I could jack up the car and poke around, but I'm not expecting these mounts to work on a Gen 2.
**Double edit: AVO Turboworld used their same trans bushing insert for 2016+ manual trans on a Gen 2. Whiteline offers something similar
