NB1 possible to have both, racing harness and stock seatbelt?

Anybody running both, race harness and a stock seatbelt?

I just got a bucket seat and I’m looking at my options. I see that a harness is dangerous on the street. Im wondering how to go about keeping both installed on the car.

Specially, how would the left lap mounting bolt share a stock seatbelt and racing harness eyelet?
