Here's a better shot of the rub. The previous photo was a little deceptive on the angles. It will be impossible to grind/cut the end of the fork without removing the master cylinder first, and it doesn't matter whether the fork is forward or back in that regard. What I ended up doing for now, while I wait for a new plastic inlet from Tilton, is to mark the rub area with a black magic marker to see if it is still rubbing or not. I'll try and get the car out for run when the weather improves.
