seats for DA

My drivers seat got chewed on by the previous owners dog and it has a pretty big hole in it. The problem is that I want to put race seats in it and i can afford it but i have automatic shoulder belts. The belt return is located on the seat.
I've tried googling it but no help there. Is there a way to put normal belts in there I really don't want to have to go with a harness because the back seat gets used pretty often. .
BTW i use my car for autoX and it's my daily driver.
It's a 1991 Integra LS special hatchback.

thanks in advance
