Donl,
The conversation above is a little confusing.
1. The door seal is a continuous piece (a foam rubber seal) that is glued to the perimeter of the door and has a metal "cover" at the bottom of the door (on the door). This seal is the same from 1947 through 1961. If you had two pieces glued to the door and they did not have the same cross-sectional profile, they were not original-style seals.
2. The cab windlace set are two pieces of rubber that are attached to the cab. One piece of rubber is attached the cab floor and covered with a metal strip. The other long piece of rubber is different depending on your year (and depending on whether you have screwed-onto-the-cab metal retainers or if you have a broken channel around the cab door opening into which you slide the longer piece of rubber windlace. The two pieces in each door windlace set have different cross-sectional profiles.
