| Drill a hole in the feedneck, not many more options. Every one I've seen had holes in it for that purpose.
As far as the pin goes it should be solid and have only a little side to side slop. Unfortunately the reg design changed a few times so pin length (and even diameter) could be anything. I've done ones in the past that had no pin (or a roll pin) and I do it by trial and error. Just long enough to push the seat about 1/16 of an inch (IIRC, haven't had one open recently). If someone has one open they might be able to measure how far the pin stick out. I haven't even unpacked yet so I can't be much help.
