Now that I've gone back an looked at it, and compaired it to my S-10, they are mounted on the right side. I just assumed that the one that was rusty and locked up was the passenger side, since it was in standing water.
They aren't mounted pointing straight ahead, but I don't think that would matter for the inertia lock. I took the one that was locked up apart to try to free it up. The inertia lock works off of two little pengilums that can swing in any direction. For myself, it doesn't matter anyway. By the time I get them pulled out far enough to wrap around my big ***, there isn't any more belt to unwind! :lol:
