We needed to shorten and modify the driveshafts to hook up to the new, bigger, axles. We tapped JE Reel Driveline in Pomona, California, to help us with that. We didn’t want completely new parts, but our front driveshaft was cooked so the company ended up rebuilding it at the same time. The front driveshaft was shortened, got a new male and female splined slip-yoke, the CV was rebuilt with new U-joints, the AAM-specific yoke welded on, and then the entire thing was balanced. The rear shaft had been recently rebuilt, so it was shortened and the proper flange added to mate with the rear axle yoke.
