What would be the best way to hook up, 4 point harness seat belts in a 1997 Civic HB ? I thought to take out the bolts on the back of the seat rail and replace them by same size bolts but with eyebolt one. But i can't find the exact eyebolt size to fit in there? Anyone has a idea of what size those bolts would be? Or anyone has already install 4 point harness seat belts in a 97 Civic HB and could help me out on how to do this. I wanna be able to put the 2 seat belts on and still be able to sit people on the back. So anyone that could help me, it would be really nice. I have been running all that day to try to find bolts and how to do it. Thanks Alot.
