Brent,
  I noticed the same "nothing fits" problem according to Crutchfield, so I
  called them and asked why any ICJ chassis wouldn't fit.  They said it's
  because the bus has a really shallow cavity -- if you pull out the ashtray,
  you'll see that there's a member in there that the back of the stereo butts
  against.  I bought the Pioneer DEH-P4400 because it's particularly shallow, and I'm
  _still_ going to bend that piece of metal out of the way, because things are
  so tight in there.  Anyhow, since our vehicles are ICJ-sized in width and height, you just have
  to do some creative bending / hacksawing if you want a different head unit
  in there.

Best,
d.
