Hi Jesse,
Thule moved away from the Traverse-feet and discontinued the fit kits that fit them so you're unfortunately looking at replacing the both the feet and fit kits. For the 2012 Prius V you would need the Evo Clamp Feet for Thule Crossbars# TH710501 and Fit Kit # TH145129. The 2020 Prius Prime would need the same Evo Feet # TH710501 but a different Fit Kit # TH145029. view full answer...
Hello Duco. The best course of action really depends on what you intend to do with the hitch. If you plan to tow a small trailer, you can simply buy a ball mount that is compatible with the 1-1/4" hitch.
If you have a bike rack that goes with a 2" hitch, things get a bit more tricky. There are adapters like the # HTAD which will convert any 1-1/4" receiver to a 2" receiver. The only downside is that using an adapter like this will decrease the tongue weight capacity of your hitch my 50%.... view full answer...
