Keep at it...and as you fit and align the doors and floor - post the pics here and others here will guide you...and by sharing you will be showing others who need to do the same. Hat is off to you... one step at a time - walk away at times if you need to, and come back to it with renewed energy and fresh eyes. Others here with the same cab type may be able to take measurements for you and post photos here of those measurements to guide you.
