I have a 2008 club car precedent. Just installed seat belts as they’re required where our cart runs. Bought this kit from amazon https://www.amazon.com/dp/B07XKGR957/ref=cm_sw_r_cp_api_i_.jvFFb2J52X6K
But then I also needed a bracket to anchor the seat belts to. Your Precedent might need it too. Picked one up from Buggies Unlimited for $30.
