I just got a new barrel from kenbev, and trying my first barrel fitting. I have the hinge to the correct depth, and trying to work on the latch. As I close it it pulls down on the striker but I cant figure out how much to take off. I dont want to take to much and skrew up a realy nice barrel. Also, the fritting instuctions say to hont the latch shelf down. I know this may be a dumb question but do I hone the top or the back of the latch shelf.
