A pair of vise grips, 8 inch adjustable wrench, flat head screw driver, sharp knife, deep 9/32 - 5/16 - 3/8 - 7/16 - 1/2 - 9/16 - 10mm - various extensions - swivel ( all 1/4 inch drive...gear wrench brand ), spare fuses, cutting pliers, flash light, spare bulbs, flat repair plug kit, and jumper cables. If traveling I take one of those hydraulic jacks in a case. ( I hate scissor jacks ) could do the same size socket in 3/8ths with a 3/8th ratchet.
That's also my junk yard bag. Gear wrench has a lifetime replacement anywhere that carries gear wrench products....that's just about all of the parts stores. If it breaks just stop and exchange it. Mine hasn't broken yet. I don't try to remove lug nuts with a 1/4 inch drive ratchet though...I have removed an explorer intake in the JY.
The solenoid won't leave you stranded but may keep you from starting the car with the key. Clutch cable may pop but you can drive without a clutch. Start in 1st, float the gears, cut off to stop and put the shifter back in 1st. A shoestring will work for the throttle.
