I have a new (used) wiper motor to install in my 99 Tacoma.  Removing
the old motor is a snap, of course, but how in the world do you get
the linkage from the new motor to the blades put back together?  There
is a very small hole in the firewall to work through, and I can get
the female part of the "ball and socket" type joint line up with the
hole by manually moving the wipers, but I can't hang on to this piece
and install the motor at the same time.
If I let go of the internal part, it just drops out of sight.  I
tried removing the plastic grate that is between the hood and
windshield, assuming this would give me a way to access the wiper
parts from the backside, but it does not.  Any help would be greatly
appreciated.
