First, Is it a long rifle or a carbine? Carbine stocks a very hard to find. Also they are not interchangeable with the long rifle as the trigger-guards are different. From what I have been told most of the carbines were exported from Norway and quite scarce even there.
I have only seen one long rifle stock for sale on e-bay (and I have been checking for years) it sold for over two hundred. And one carbine stock for over $300.00. Plus you would need the barrel bands, handguard, ???
I imported a long rifle stock from Norway last year for about $300.00 with bands and handguard but I am saving it for a pre-1899 Krag that has been sporterized, although I am still looking for a nice one.
I might be mistaken but I do not believe the U.S. Krag stock will fit, I know the Danish stocks will not.
Best of luck, John
