The chart below has the information you need. The information given would be different for different riser lengths, so hopefully your 19” riser is the only one they made for this bow. A 58” bow with a 19” riser will stack if your draw length is more than 28”, but you say you don't have a long draw, so hopefully this will work out for you.
In the future, questions regarding equipment should be posted in PowWow, but since I was curious and the information was easy to find, I went ahead and posted the answer here.
