Just a reminder to those interested in the GM tow hooks - - make sure you purchase the SET of hooks (two hooks, four bolts, and two screw plates) instead of the individual hooks. The set lists for about $20-25, but a single hook (without bolts, screw plates) will run almost the same price.... Don't know why, they just price them that way.

P.S. The GM hooks mount right up to the frame rails for '91-94 Explorers. You will need to either remove the front air dam or cut two notches to access the hooks. All that is required is to remove the front bumper and drill an additional hole in each frame rail, then slide the screw plate into the frame rail and bolt them up.
P.S.S. Ray - Did you ever get the data I sent you for the Con-Ferr roof rack??
