Closet Door Ball Catch

The ball is missing but I was able to remove the part containing the spring. I cannot find the size of the one installed and since the hole is bored into the door I need to find one the exact size. There is no manufacturer listed I can find. I recently bought the house which is 2 years old. The casing for the spring is 1 3/8 in long, 1 inch diameter across top where ball fits, 5/8 diameter on bottom which fits into the bored hole. Any help would be appreciated. Thank you.
