First off, holy shit did I get a lot of support from you guys, and quickly! Thank you so much.
I called the mechanic a little bit ago and discussed all the installation tips, etc. with him that
you guys mentioned. He confirmed that everything was installed that way and he said he's
done numerous Subies, some with SPEC clutches even.
He measured some tolerances on the inside spline grooves and found one very tiny area that
was a little different, i.e. a few thousandths of an inch. He ran a light file in there and found
a small metal burr in the paint. He filed out the burr and smoothed the paint, reinstalled and
everything is peachy. I'll pick it up in a couple hours.
