I received a set of Grove brakes for my 235 last week.  I found that they
were about 3/8" wider measured from outside of caliper to axle tip than the
Matco brakes.  On my 235, the wheel would not retract all the way into the well before the
axle hit the underside of the top wing skin.   I considered modifying the
axle, but this would have moved the caliper into the space occupied by the
outer gear door.  So reluctantly, I returned them to Grove.

It appears that the wheel well area of the 320 wing is somewhat deeper than
in my 235.  Bob Belshe
