I stumbled into a good deal on a new-in-box, unopened Yukon axle kit. It includes new wheel studs, wheel bearings, and backing plates. These are 31 spline for a 66-75 EB width housing with big bearings and 1 3/4" brakes. Normally $317.88 from Wild Horses (plus a hefty shipping fee). $200, or swap for good condition shorty headers (potentially plus cash on my side for really nice ones).
