glad you got it figured out,
what i have found, is that some 03,s have a real nice fit and they fit tight as well,
A3 stocks are fit a bit looser to take the stamped parts, though some stamped parts will work in both, some wont, bent or not, youll see a variation in corners, and sizes with stamped parts.
more so on trigger guards, then anything else, more bends ect.
if they were heavy handed when taking the rifle apart, they will indeed get tweeked.
best bet is to stay with milled parts..and use real GI, not import junk.
