Those look good. Do the seats rub against the door panels? The side bolsters on my Scat Elites hit the arm rest and you can’t get the three point belt passed them with the door closed.I found a set of black leather seats from a '99 Mustang. Very comfortable and a good fit. I'll try to find my pics.
Mounting/routing the "three-point" belt that way is dangerous. There needs to be an upper mounting point securely attached to the car body up high. All this set-up is really doing is providing a potentially compromised lap belt and a cosmetic shoulder restraint. You really should just use a standard lap belt or install the correct upper mount. The way it is now in the event of a crash the occupant will fly forward, the force breaking that upper plastic guide off creating the possibility for the broken piece to slice across the neck or face.
Sorry I'm not seeing that. Your belts appear to be coming out of the inertia belt reel up to the headrest mounted guide then down to the floor anchor point beside the seat.I have a mount point at shoulder level in the door pillar. The back side can be seen in the pics.
Looked again at the clearance between seat and door. About 2 inches at the seat and about 1 inch between seat back and the armrest.
If you look just above the reel you will see the belt threaded thru the mount that is resting on the reel. It connects to a stud at the top of the door pillar. You can see the base that holds the stud at the top of the door pillar. I had disconnected it while installing the new seats.Sorry I'm not seeing that.
