I bought one of those tiny ratchets like you used from from Horror Fright the found a nut driver kit on the counter at Ase Hardware. The ratchet in that kit is designed similar to the typical larger ratchet. The ratchet came in a metal box with a dozen or so bits like phillips, slotted and other type bits. Had it included an extension it would have been a lot nicer but for 13 bucks it is what it is.

Those tiny ratches saved my bacon when I was working behind the dash on those 7mm plastic nuts which old the wood trim to the dash.
