Alvarez Masterworks replacement nut

[Nick5182]

Hello, all. I'm new to this forum and need some help. I have an Alvarez Masterworks MDA66SHB acoustic guitar that I need a replacement nut for. A little back story, I keep it on a stand in the far corner of my living room, and my dogs got a little rambunctious playing a few days ago and managed to knock the guitar and stand (yes, the neck retainer strap was in place) over, causing it to fall directly on the bone nut, which shattered the nut into about 20 pieces. Unfortunately because of this, I can't measure the nut with calipers to accurately find the original dimensions in order to find a replacement. In all of the research I've done, the only information I've been able to find is that the original nut is 1.75" width and was made of bone. I'd like to use a tusq nut for replacement. If anyone knows the dimensions of the original nut or could supply me with the model number of a tusq nut that would be close to drop-in, I would greatly appreciate it. Any help with this would be amazing. Thanks in advance.
