There is very little space between hte retractor and the front seat, even on buckets you'll likely lose a small amoutn of travel in you seat movement. If you need your seat mounted back as far as possible you may need to mount the retractor to the floor and run it through another guide mounted where this retractor is currently mounted, you will however need a horizontal mounting kit instead of a vertical kit to do this and I have no idea how it would go as I've never done it.
