Looking for replacement lockset

A quick learner from Baltimore, MD says:
I am looking to replace an old Pado storm door lockset (with 0796 stamped on the interior). I see that you have recommended part 40-049 in the past. However, I would prefer a satin nickel or chrome finish. Would part 40-183 work? The measurements are almost identical, but I think the distance between screw holes on the interior/exterior faceplates are 1/16" different. The measurements I was able to take on my existing set (though probably not entirely accurate) are 6 5/8" between screw hole centers on the interior/exterior and 6 7/8" between screw hole centers on the edge (where the deadbolt sticks out). The dimensions of the cut openings in my storm door are 6 1/2" x 3/4" on the interior/exterior and 5 3/4" x 5/8" on the door's edge. The door itself is about 1 1/2" thick. If there are multiple options in a satin nickel or chrome finish, please provide a complete list. Thank you.

Thank you for posting. I think our 40-183 is a good place to start. I've never seen this type of handle with those exact measurements. I would double check your dimensions and make sure you're measuring the distance of the screw holes from hole center to hole center.
