Sent you a PM.
There are several things you should know about rebarreling an LW. First, the alignment pin is proprietary, it's domed on the top instead of squared off. You'll have to take a dremel and knock off the corners so the new barrel will seat into the upper. Secondly, you'll need to reuse the barrel nut (unless you bought a spare) but it's basically captive on the current barrel since the gas block is pinned on with a taper pin and good luck getting that out without a press. You can cut the gas block underneath the pin and then hammer it out but without relieving the tension it's near impossible to just beat that pin out with a hammer. Just an FYI.
In summary, it's a whole lotta work.
