1. A drive tool for an upper end fitting locking arrangement, comprising: a. a driver formed from a shaft having a first end having a diameter larger than the remainder of the shaft and a second tapered end, said driver having a radial notch and a plurality of axial slots in communication with the radial notch at a selected distance from the tapered end;  b. a positioner rotatably and slidably received on said driver at the radial notch and axial slots;  c. a set screw that extends through said positioner and is received in the radial notch and axial slots in said driver whereby said driver is movable relative to said positioner between a first normal position where said set screw is located at the end of one of the axial slots distant from the radial notch and a second operational position where said set screw is located in the radial notch;  d. a spring received on said driver between said positioner and the larger diameter of said driver whereby said spring resiliently biases said driver toward said first normal position; and  e. a wrench received on and attached to said driver between said positioner and the tapered end of said driver, said wrench having one end provided with equally spaced slots around the circumference. 2. The drive tool of claim 1, further comprising a drive head attached to the larger diameter end of said driver.
