Another thing to consider.
If you are living near the great lakes you know there is tremendous humidity in the summer. Factor in a few hundred for a good dehumidifier for your space if your house is not climate controlled where they will placed. Humidity and 57s / 63s dont mix well. In discussions with a couple of rebuilders the message was the same. 57s are much more durable than 63s in this area. Totally rebuilt 63s can be destroyed in a few years if left in high humidity.
Good luck
