If yer looking for the hex wrench to tune the plastic hex nuts on the pull rods, I believe a 3/16" hex nut driver will get you by in the short run. Available at Sears, Home Depot, etc. Don't twist too hard 'cause the nut driver's depth is short.
George L sells tuner nut wrenches that work nice too. I believe his nut wrenches are closer to a "deep well socket".
If you wanna get really sexy buy the Sears 1/4" drive socket set complete with Speed wrench and deep well socket for the 3/16" nut.
