Most of the DAS bushings I've removed, for the first time, had a little glue on them. Don't know how much, or what kind of adhesive Border uses, but no doubt they're glued in. Only thing I suggest is, be sure to use a bolt in those threads and apply a little more pressure--but like you said, not too much.
Oh.... and btw.... Like Rusty, I made a wooden receiver years ago. When you change these things out as much as I do, it comes in real handy.
