B is to new for a 1st gen ranger, i don't think first gen rangers had that style trans shifter boot. Taht was more a m5ord shifter boot and don't think those were released until 89 (2nd gen).
Is the 4r553 or 5r55e longer then an a4ld? If so then I would assume B would be what you want.
Didn't notice before, but i Think pic A is "4x4Junkie" 2nd gen B2 (on another site)....it has the extra handle for the 1350/54 doubler in the pic.
