The chain slider is also held in place by four little snap protrusions that fit into top and bottom holes of the swingarm, plus the bolt on the side.
The tabs used for the bolt on the side overlap, with the bolt fitting through the combined hole and into the swingarm. Those tabs may make the job a bit difficult passing through the opening near the front sprocket area.
On the surface, it looks like it's doable. But I replaced mine while the swingarm was off during an engine swap, so I can't rightly say.
As an aside, my original chain slider was still in good shape, and I could have used it without any worries, but I replaced it nonetheless as good insurance. I still kept the old slider as a spare.
