However, the LR TD5 had some very good production engineering values developed by LR.  (not real good for O/H though, as I understand).  Hence Ford perhaps kept the intellectual property rights of the design, after all Ford owned those rights at the time of sale to TATA..............and the Landie TD5 not used in another TATA product????
As an aside re car companies perfidy :0)   Paint on my SVX (comes from Rangie ie "exclusive" Santorini Black, a metal flake black) is identical to paint found on  a Ford F250 (parked mudguard to mudguard :0) We didn't actually check the codes)
I do admit to have not looked under the bonnet of a Ranger or BT50 but the sound is redolent of Landie TD5.
