Correct Allen Wrench size for the rear caliper carrier removal bolts on an 87 4kq

[Cade Carvell]

Hello,
  I was working on my rear brakes today, and discovered that the lower
caliper bolt, wouldn't slide.  On inspecting further turns out that the
caliper carrier is corroded inside the slide areas (The pins that slide
in and out).  Anyway, called up local VW Dealership to get the part
ordered in, since I don't take any chances on trying to fix these kinds
of issues with brakes.  Anyway, it will arrive in a few days.  What size
tool is it that I need to get the carrier removed?  It looks to be an
allen wrench of sorts, but I am not sure on the size, and since it is
that large, they don't exactly sell them in kit form.  I have to buy one
at a time, and I woudl like to get the right one the first time.

Any ideas on the size?

Thanks,
