Compititon seatbelts with a bench seat??

[PT Sportwagon]

I am eventually wanting to do some pro-touring events. Which will more than likely be some track time, and/or autocross. I don't think my 40 year old lap belts would be the best for safety. Right now I am wanting to keep my wagon some what stock, with the bench seat. I may decied to go with buckets before I am done. What would be the best and proper way to add compititon seatbelts to my bench seat. use the factory lap belt mounts or ??? Or should I look seriously at buckets???

Thanks

I would never add a 4 or 5 point harness without a rollbar.

I would look into adding a 3 pt retractable harness. And maybe add some headrests.
