What direction have others positioned the Z bracket? Facing forward or backward?
I've seen some photos of it facing forward with the reels sitting on top of the seat back, but to get the bolt fully into the captive mount, the seat back will need to squash down quite a lot, and it doesn't feel like it will.
Positioning the bracket backward might allow the inertia reel to clear the seatback, if the bracket was longer.
Also, on the drivers side, the locking mechanism that protrudes to the side appears to foul on the C pillar, given the belts aren't "handed".
