Believe you Bo, but it's not listed as a factory option for the 88s. But as it always is, nothing is written in stone. There were probably lots of parts leftovers at the dealers and maybe some found their way into the 88s for a fee. Never have seen an 88 with one, and I looked hard for a couple of years, but that doesn't mean much. Most of the old XJ/Waggys from that era had been "recycled" now unfortunately. If you're patient enough an 87-92 MJ D44 will show up before the older XJ D44 since because of the age.
