What all y'all said. I just don't know why LS didn't include them.

Mr. H. That would do nicely!!! A metal pilot might/probably work (he sits pretty close over those main gear) ... I don't think anything short of that would be massive (heavy) enough. Would be worth a shot, - I think I figured that if I do it before I close the halves up, that a single BB or a small piece of lead would fit behind the dial panel but that wouldn't even touch the weight problem.
And thanks... it turned out better than I was expecting.
EDIT: Also not included is that little intake bit there on the bottom.
