Multi-point Mortise Latch replacement

Hello, I am looking to replace my locking mechanism as the latches for the mechanism are no longer able to slide from a locked to unlocked position. The piece that I need looks very similar to the 82-239 model. It is just under 10'' long, just over 1/2'' wide and 1-1/8'' deep. I was just interested in seeing if this part (82-239) would be a suitable replacement before making a purchase.

Thank You in advance,
Eric
