When I purchased my 1988 XJ-S last year, there was no headliner and all interior trim had been removed.
Since then, I’ve removed the passive seat belts and retrofitted three-point seatbelts from a mid-80s XJ-S.
Are these pieces now not needed, and can be thrown away? I know I’ll eventually need to buy some interior trim from a mid-80’s XJ-S.
Thanks for any info.
