Oh it will fit for sure. The 271A is not as wide as the stereo head unit. I needed to make up some spacers for the side brackets to hit the Kenwood and there was some bending and drilling holes in the correct places as well. Not a big deal. There is some space on either side of the unit, but it really doesn't bother me. Depth and height are perfect.
My antenna is mounted on the rear left of the hatch so I needed a short extension on the cable. Again, not a big deal.
Somewhere in this section I did a writeup of my install before I got my licence. I originally had the Kenwood mounted to the rear of the center console where I had my old CB. I moved it after I realized how stupid that was. You need to see the display once in a while.
The front firing speaker is loud and crisp. Perfect for a dash mount. The 281A is the updated version of my 271A, but according to the 271A Yahoo forum, they are almost identical. Its a good unit and I like the Kenwood mics better than the Yaesu mics. Heavier and more solid feel to them.
