That is a Chinese stock for a pinned barrel action and you have a threaded barrel action. There is 1/8" difference in the location of the cross-bolt in the stock because of the following;
Threaded barrel actions rest on the cross-bolt at the locking/indexing collar and are 9" from the back center of the in-letting to the rear of the cross-bolt. Below pics are of a threaded barrel action.
Pinned barrel actions rest on the cross-bolt at a machined cutout area at the front bottom of the receiver and thus sit at 8 7/8" from the back center of the in-letting to the rear of the cross-bolt.
