need mortise for an Andersen

Question

I tried to buy a Swisco lock mortise (40-198) for my new Andersen Storm door handle set. It is not the righ one.

Do you have a better fit I should use?

Take a look at the 40-194 mortise lock see if this would be a better fit. Take note that the back set is 7/8". It's important to make sure this matches up to yours.
