Can  anyone tell me if the OEM carpet easily separates into the three
sections  during removal or how the three sections are connected if at all?

My  upholstery shop wants me to leave it for them to remove so they'll have
a  better time installing new but I've got it sold and am afraid they're
going  to hack it up like a residential installer  would.

Looking at it closely, its fairly obvious how the front carpet comes  out.
Front piece is one molded section.  if you have an auto trans  you may have
to remove shifter housing or slit the carpet where it goes behind  it.
there may be black plastic dome shaped nuts holding it to the front  cowl.  may
or may not be glued to cork backing pad.

middle walkthru is another piece, you have to remove the metal strip that
holds it at the rear - the phillips head screws penetrate thru to underside
of  van and sometimes are rusted solid. may or may not be glued to cork
backing  pad.

the pedestal carpet is glued down with this heinous black rubber urethane
cement at the edges along the rear and battery boxes.  use a flat bladed
putty knife and a hairdryer.   along the front of the pedestals remove  the
plastic triangular trim piece, and use the putty knife to pry the metal
channel lips back to remove the vinyl carpet welting at the top.  go  slow..or
you may rip it.
