The Pietta shoulder stock will fit either the 1860 Army or the 1861 Navy, as the brass clamp guide is short enough to let the clamp pull up to the Navy butt, however a lot of thread projects up when fit to a Navy..
The Uberti shoulder stock is specific for the Army or Navy, as the clamp guide and the clamp's threaded portion is a different length for each.
The 1851, or the Remington or SAA stock use the long hammer screw mount, and none of those guns have the cut in the recoil shields or butt that the 1860 and 1861 Colt type has.
As previous responder mentioned, often the wood is too wide by a bit to pass through the wings of the shoulderstock, and the wood pistol grips need to be narrowed a bit at the top to work.
