Hello Hoyt,
One of the places with the tightest tolerances, is the rear part where the rear toggle link meets the frame. If you have been grinding on the 'slots' you see in the frame, you are probably looking at a lot of fitting on several places to make it go back together. Depending on the depth of the grinding, you may even end up having to grind the rear toggle link (though, very little could be done there, the 'cut' needs to stay sharp).
I hope this is not the case.. and wish you good luck getting it back together!

Btw. I quess you know that the S-lever needs to be in the right place, not in the magazine well or behind the spring notch.
