If your top and bottom fittings match our 19-005 and 15-005, respectively, then the Series 380 is exactly what you want. The Series 380 additionally can be used for the left or right hand side interchangeably, these aren't specifically handed.

Your old stamp, 29-6, matches our 2960 option. These should be the same for both the left and right hand sides.

Finally, concerning the 18-166, it is only one of dozens of potentially compatible top sash guides. The only way to know for sure is to carefully compare the dimensions we show on on its store page to your part.
