Measuring from the outside would be fine if you aren't flexing the
flywheel when measuring. Prying with a screwdriver while measuring
endplay near the edge of the flywheel will give erroneous readings.

I am willing to bet (my currently not running '87 Westfailure) that your
endplay is within tolerance.
