Jayme...
If this is a 3/8-10 bolt w/ threaded insert for bumper connection,might it not be a fairly standard shelf item from Prather, etc? If not, why doesn't McDermott contract a run of them made... There are many D line cues in players' hands... (I own 2 - one which I had made thru the McD "custom shop" back in the D line days.)
Seems irresponsible for McDermott not to have either a ready supply on hand or a ready source available - considering we're talking about one of the single most high quality and successful production cue lines ever sold.
