[Elecraft] KPA-500 construction problem/question

[AG0N-3055]

I received my KPA recently as a kit.  Assembly has gone well to this
point.  However, I cannot get the fan connector to slide down over the
very long pins on the PC board.  They insert and feel like they should,
and like they are engaging properly with the pins, but it lacks 5mm of
going on flush with the plastic to plastic contact.  The pins appear to
be twice as long as they should be.  I could clip them, but won't do it
until I know that's what I should do in case I'm doing something else
wrong.  I have pushed and wiggled so hard that I am flexing the board
more than I want while trying to get the connector mated.

Anyone else have words on this?  Yes, it is the right connector (P7).
