N7WB is an early 235 (#135) and I couldn't figure out how to make the
brackets work. With the gear retracted there wasn't room for the doors to
fully close. I adjusted the outer and inner gear doors, cut out the inner
skin and foam around the gear casting until the middle doors would close
and then opened the opening another 1/4" all around and bonded a 2-bid
patch to the outside skin over the opening I had made. I then laid a
6-bid strip, 2.5 inches wide from the front of the door to the aft side
(leave room for the lip on the wing cutout).  I painted the entire casting
with release agent.  I then retracted the gear, filled my cutout with
dry micro and pressed the middle door into place, blocked it there with a
jack and let it set up. I then drilled two holes through the gear doors
with and into the gear casting with a # 21 drill. I threaded the holes in
the casting 10-32 (would have better to use 10-24) and opened the holes
in the doors with a #9 drill and counter sunk them. I screwed the doors
to the gear casting. The doors fit perfectly and have given me no trouble.
I have changed the compression donuts once, and by keeping the stack
the same thickness the doors close in the same place.
