It may have a close cousin that was installed on Cortina‘s, i’m not quite sure.
but I am quite sure the steering column is in fact a MK1 UK Capri steering column including the turn signal stalk and the ignition lock assembly.
To allow the column to be used in the Pantera, DeTomaso actually removed about a 12 inch section of the steering shaft and then welded together the top and bottom sections.
