Craig, just doing some research to see how I could help.
Your ADL only has a trigger guard bow, correct? There is no mag box/floorplate integral with it, correct?
If you go to the PT&G website (Pacific Tool and Guage), they sell ADL trigger guard assemblies that are aluminium in varying colours, quite cheaply too, around 25-35 bucks a piece.
I'm sorry, my rifle is the BDL type version with trigger bow and floorplate as one piece and only 2 holes in it, my bad.

Cheers.
