The second member is secured over an oil well, such as to a blowout preventer. The first and second alignment members are secured over the second member, with the alignment members being adapted to rock with respect to each other due to each having inverted sloped portions. The first member is secured over the alignment members and is adapted to receive a stuffing box. A polished rod may extend through the first and second members. By adjusting bolts securing the first and second members together, and by action of the alignment members, the polished rod and stuffing box may be brought back into alignment if misalignment occurs.
