Outer Limits 4x4 Board

Hey all, my brother and I are currently in the process of making a set of rock sliders for his 80 series.
So far we have made the side rails? sliders? (not sure of correct term) but are having troubles with an idea of attatching to the chassis.

If anyone has any pics, or ideas we would love to hear them.

Thanks
Mike
