I have seen these mounts at Wal-Mart for like $7 i think...I'm not sure i would trust them to hold the mag onto the roof because they are plastic clips...getting hit in the head by a solid aluminum 2.5" diameter rod is not my idea of a good time off roading. I made one for mine that uses hose clamps which i welded little "T" handles to the screws and welded a little strip of metal betweel the two clamps and drilled holes in that so that it will mount. I have it screwed to the drivers side of the center console. I can post a picture if anyone wants...I think i'd actually prefer the clips for my application, but the rig i made up might be better for the ceiling mount.
