Depending on your vehicle, swap out the regular Hi-lift handle for a piece of DOM tubing long enough to make a replacement or reinforcement for your tie-rod or draglink. Ruffstuff makes some weld-in threaded bungs that work great for something like this.
Buy a 1/2" pipe nipple 8 or 10 inches long, makes a great cheater for rachets or breaker bars, also makes a good splice for heater hoses.
slide a length of heater hose under the seat for a siphon, spare hose, grommets for other hoses, ect.
Stuff the center of a roll of duct tape with 550 cord, a small razor, a little tube of super glue and zip ties. (add JB weld if you like). Seal the sides with more duct tape to keep all your adhesives in one spot.

Cut a piece of hardware cloth to fit your radiator as a rock guard.
