No, the "new" (at least 85/86) setup IS 3 separate pieces, but according to the parts manual, you can NOT buy it as 3 pieces. (listed as 3 pieces, shown as 3 pieces, but 2 part numbers. Make sense? Of course not.)
The separate piece is the trim one. The piece that you would see if you were sitting in a complete unmolested truck. The boot/retainer that come together are not physically bonded (from the picture) just not available separate. Make sense?
In other words, if you order 14071955, you will get the boot, and the metal(? not sure if its metal, but thats all I've seen in person) retainer that holds it in place. From the pic it looks like as installed the retainer (not trim plate)is made out of "U" shaped steel (as installed, the points of the U face towards the roof) if that makes any sense. If it doesn't, the retainer is still in the shape of the shifter cutout on the tranny tunnel, but instead of the metal plate being flat steel, its U channel steel. All by itself, (without the trim plate) you'd probably assume it was supposed to go with the points of the U facing the ground.
If you order 14032789 you will get ONLY the trim plate (not sure if metal or plastic) that hides the above metal retainer from passengers in the truck, and makes it all look pretty. /forums/images/graemlins/smile.gif
At least with this 85/86 manual I can't see how a parts guy can make a mistake if he's actually looking at a pic (and I think they can) since it CLEARLY shows the 3 pieces in the order that they are bolted to the tranny tunnel. No scanner or I'd send you the pic, but it is that simple.
Boot goes on first. Then upside down U retainer. Then the trim piece.
