What? Did you really think we would leave you hanging without an install of our mail-order 9-inch rearend from Currie Enterprises ("Mail-Order 9," Aug. '08)? Think again. We recently followed along with Currie as they produced one made-to-order rearend for a '70 A-body Chevelle. If you recall, the '70 Chevelle was purchased as a leftover project car, and we've been following along as owner Robert Varoujanian from Santa Clarita, California, has been converting it from an all-out drag thug into a much more pleasurable street/'strip sled. In order to achieve this, we had to remove the original rearend, which incidentally was in great shape, only it was encumbered by a spool and C-clip eliminators, and the short gearing wasn't going to allow for any enjoyable street excursions.
Currie has the ability to get a high-quality rearend built exactly to your specifications with door-to-door shipping. It's important to note that nothing is too crazy or out of line for Currie. In our case, we got our 9-inch built for the stock dimensions of the '70 Chevelle. For added strength, we added stock-length 31-spline axles, a 1350 yoke, and a set of 3.50:1 gears with a limited slip, and even upgraded to Currie's Explorer 11-inch disc brakes for improved stopping power.
Before we could get the new Currie gear up and underneath the frame of the Chevelle, we took out the old 12-bolt by first removing the rims and tires and then unbolting the whole assembly from the upper and lower mounts. Since our new Currie unit was raw, we completely disassembled it on the crate, removed the brakes and axles, and gave it a couple of coats of semigloss black paint to protect it from potential rust. Once the paint dried, we spent the next couple hours swinging the new unit in. Honestly, it was simply a matter of replacing the old with the new. It only required simple hand tools and a few hours out of a Saturday afternoon. Even better, we were able to use all of the hardware we took from the old unit. With a little more work and time, this '70 Chevelle will be ready to lay down some rubber, hitting everything from the street to the 'strip and slicing around cones.
