Yes, the box is wider, but will bolt right in,put one in my 37 . If you feel comfotable and have a manual,, disassemble the box, the barrel roller races can be worn or dented , makes it impossible to get a proper preload on the steering worm. Also check the sector shaft bushing, another potential wear area.Use sealer(not RTV) on the worm gear adjuster threads,sector adjustment screw and the bolts.That along with a new seal will keep in 90 weight gear lube, Grease is a poor lube choice,can't get to the recurcilating balls.Or if you can find it,use the heavy GM steering lube.The 41-47 box makes for much better steering.
