Inland Empire Driveline Service built Dave a custom aluminum driveshaft, which runs to a "hybrid" 8.8-inch live axle. This is standard practice in road racing, where the well developed live-axle systems have proven more predictable than any Cobra IRS system to date. The hybrid in Dave's axle refers to the larger "Torino" bearings in the outer ends. The axles are Currie Enterprises 31-spline road-racing parts. As is the engine, the rearend is lubed with Red Line products, which, not incidentally, are cooled via Dave-fabbed transmission and rearend coolers.
