Got the drivers side installed today, but do not slide very well due to the rails being pushed together. I don't know if my install was wrong but I tried all of the different settings and got the bolts in. I wonder if other rails are this hard? They are basically fixed mounts.
Mine don't slide well either... i guess that is the drawback to having individual side sliders vs SOS type where they are supported in the middle area. Hopefully I'll have some time this weekend to re-mount my driver seat.
