Unsure of that particular bracket, but (MY OPINION ONLY) if you are converting to Fixed stock that looks to be a good start.
It does not have the quick disconnect lever and features, (good).
The threaded holes are what you need, because you would bolt from the bottom up into that bracket. I had to tap my thin metal from the countersunk area to get what you have. The pic below shows the most popular configuration, you can see that once the bracket is in place you have no way to go from the top down. The circled items are splined nuts inserted in the wood.
The large hole on the QD bracket is a male pin that goes into the back of the gun. In your case you can use the standard tombstone shaped nut inside your gun, it will stick out about 1/8 which will go into that hole you have. Then keep it together with a washer and 1/4 -20 allen or button head allen bolt. your only job then will be to dimple (drill) your stock to clear the bolt and washer.
Is your gun a rifle? or Pistol? or did it start as a receiver?

There are pics of making clearance for your bolt in the link
Also you don't have to do the part about shortening the tombstone shaped nut since your bracket is already suited.
