We assembled the new right side of the rearend completely before placing it onto the center section. You can clearly see our new birdcages from Bert. Yes, we didn't know Bert Transmission made birdcages either, but they're really nice looking parts and we can't wait to get on the track to let you know how they perform. We also decided to stick with our 007 hubs from Winters. We loved the way they performed over the last year and a half so there was no reason to change.
