3-point seat belts for bench seat

I just pulled them when I put in new carpet. I drilled them into the floor just behind the door jam. maybe an inch. But it has been so many years since I did that I do not remember exactly. I do remember being pissed that I could not use the existing connectors and needed to drill into the floor. I have a appx 2" fender washer under the car so it does not pull thru the floor.

Trying to remember, I do not think I could make the bottom anchor/retractor fit where the original belts attach

I bought mine from a company that did seatbelts primarily. Not thru a distributor. I just looked around, may have been Seatbeltsplus.com
