if you have the first pod (both sides the same), you will need part 3349 - brushless offset kit. You do not need to order 3339. this gets you an extra top plate that will not fit and costs extra money. 3337 is the center standoff that you WILL need, and if you're handy with a dremel, that's it. If you don't want to cut the left bulkhead and would rather buy a new one, the part number is 3338.
MUST:
3349
3337
MAYBE: (if you don't want to cut)
3338
