A self supporting thong type brief has no side or waist portions and can be shaped to custom fit the wearer for substantial exposure of the midsection and buttocks area and is particularly suited for sun bathing and tanning. In a preferred embodiment the tanning brief has an interior frame formed of a length of small diameter resilient malleable wire bent to form a relatively short front portion, opposed elongate side portions which extend rearwardly and angularly inward from said front portion and converge toward each other and then extend rearwardly parallel to one another to form a longitudinal rear portion. At least the longitudinal rear portion of the frame is covered by a soft cushioning material. The frame and cushioning material is completely enclosed by a fabric covering. The brief is preferably packaged and sold in a straight configuration, and is thereafter manually shaped into a generally C-shaped configuration curved along its length to custom fit the body of an individual wearer.

In accordance with illustrative embodiments of the present invention, a side pocket mandrel includes an orienting sleeve having guide surfaces that lead to a longitudinal slot which forms, together with an adjacent longitudinal recess in the mandrel, a T-shaped channel that cooperates with projections on the arm of a kickover tool to precisely align the gas lift valve with the receptacle bore in the mandrel. The kickover tool includes an assembly of pivotally mounted upper and lower arms with the lower arm being pivoted to the tool body. The lower arm includes a locating finger and transversely extending projections that engage and slide in a T-shaped channel of the mandrel to achieve precise alignment of the valve with the receiver bore.

In accordance with an illustrative embodiment of the present invention, a gas lift valve that is latched by a latch assembly into a seating bore in a side pocket mandrel includes a guide flange that is recieved in a slot in an internal wall of the mandrel. The guide flange functions to precisely rotationally orient and to stop the insertion of the valve within its seating bore such that a lateral gas outlet port in the valve body is directed inward toward the main bore of the mandrel. A frictional restraint also is provided to prevent accidental release of the latch assembly.
