The problem comes getting the rotators in and out at places other than
where the reinforcements leave a gap.
Some fit and some don't. On my 25G I could only get the rotator in an
out at those gaps.
My accessory shelf fits most anywhere. You do have to move a few inches
up or down from the bends in the reinforcement rods.
However it's getting replaced with the LM470 even before I got it
finished. Had it durn near done, when I was interrupted.
