Welcome to Stovebolt. To make it easier to answer you need to list what year and size of truck when you ask questions.

With closed driveshaft I'm assuming you have an AD truck with a column shifter and assuming the OD is mid '50s or later. Yes, you need to use your AD issue side plate and shifter arms.
