In more realistic terms those dimensions are guite small,
.047"-.078"(3/64-5/64"). What they are really trying to say is
you want "some" clearance between the top plate and retainer.
Don't worry about there being to much cleareance, you won't
have that and even if you did have as much as .125"(1/8") you
would still be fine. The technical writer had to put something
down so he picked that for a range.
As far as the support, that was simply my way of doing it with
out hanging it from the top while I removed the rear mount, you
just want to be sure that you don't dent the pan.
