Helion Animus Diff Spool insert

I wanted a locked rear drive on a Helion Animus. I created an ez drop in spool to replace the spider gears in the differential. Using the original pin in optional. The spool is clearanced for the tabs on the ring gear. To install, remove the differential from the car. Pull out the drive cups. Unscrew 4 screws on the ring gear. Split open the carrier and removed the side and spider gears and pin. Install pin (optional) into the spool. Insert the spool inside the carrier with the notched tabs facing the ring gear. Reassemble the rest. Remember to use a little bit of light lube on the ring and pinion.
