Hi Ferrett, welcome to Outdoorking.
Be careful buying a Diplomat. The plastic gear that drives the rear drum has a limited life, and replacements are not available. For a number of years people have been fitting first, the aluminium gear which SB supplied as a service replacement, then more recently, a gear made up from a stack of steel stampings riveted together. We are told that these are no longer available, however.
I suggest you work out how you will provide yourself with a durable drum drive gear before you commit to the project. Catchers are also a rare item, but there is more scope for improvisation with catchers than with drive gears.
