Passive seat belt

is it possible to remove the passive shoulder seat belt and install the side mount one? I am not sure the Jag dealer here will fix my passive belt

Yes, i did it on my 88 with passive belts.

But it involves getting several used parts from mid 80s XJSs:

  • belt receptacles

  • three point belts/retractors with all the hardware

  • normal headliner trim piece

  • bezels for slots needed to be cut in rear quarter panel trims

  • can’t recall, but new B pillar trim may be needed?

You’ll need to remove rear quarter panel trims to remove old system, and install retractor.

You’ll also want to remove seats, so you can remove bulky retractor for passive system attached to the seat.
