The older I get, the more giant tools I buy.... 15 yrs ago I bought a used 0-750 ft-lb Snap-on torque wrench (3/4" drive) specifically for Pantera rear axle nuts. Also works for other very hi-torque car fasteners; original Mini flywheels, RX-7 rotary gland nuts, etc). Because such large torque wrenches are heavy, 3-1/2 ft long and bulky, they are often for sale used at ridiculously low prices on E-Bay. I paid $110 including shipping, in perfect condition. This model (and an even larger 0-1000 ft-lbs one) has a removable handle and a settable dial that lights up a small AA battery powered bulb when a preset torque is reached. So its a one-man wrench in spite of its size. Last time I looked, Snap-On still sells this model new.
