You can do the PDR install without changing the windshield. I did it on my '22 SS 1LE, but admittedly there are lots of details that one must get right to complete the install. Here's a thread on the install:

Some of the info in that thread pertains to the pre '19 PDRs as there were some changes after that. But you can pick thru what actually is part of the install. My '22 info comes in on page 6.
A Garmin Catalyst or the AIM Solo2 are great choices but they each do not do what the PDR does.
The PDR has easy to use full vehicle integration that datalogs lap time/lines and deep vehicle info along with video recording. Yeah, the PDR video quality sucks and the sound is terrible at high speed, but the latter can be fixed. If you care more about all the info more than the being a YouTube hero then the PDR is great. Take the data and use Cosworth's free Toolbox and Pi Toolbox software and the amount of info available is excellent. It's surprising to hear how many PDR owners do not know about the deep info that is available via the software. They think it's just a video and lap time recorder.
