something to get you going wit the mount:

the little turqoize (i'm not sure how to spell that colour) wings just before the clutch, go to the front of the mount and on top. the front of the mount is where the transmition of the drill motor slides into (from the top) a sort of
colar and it cant really move from there except a littel tot he front...

i know its vague but i really hope this helps you
