Old leaking and faded compass cartage slid out of the holder and this new one slid in. Easy and simple. Compass was swung with very minor adjustments. Elegant solution to my problem.

Exact replacement

We needed to use the old compass faceplate as the new compass did not work with the existing mount. Also, the original compass had a mounting screw in the bottom and the new compass did not, so we needed to mark, drill and tap out a hole for the bottom mount screw. Other than that is worked fine.
