I need to edit the string that is printed out for usps. We use shipworks to ship and it can only view the 1st 40 characters of the shipping field to determine shipping. I need the shipping type to be within that range.

On a completed order here is what I get
United States Postal Service (1 Boxes) (1 lbs, 1 oz) (Standard Post)

This is what I want
United States Postal Service (Standard Post) (1 Boxes) (1 lbs, 1 oz)

Thanks
