For sale is a 4.1 Torsen differential for a Mazda Miata, along with axles and driveshaft so that you can make a full swap on non-Torsen cars. The knuckles on the axles are no good, but the axles themselves are perfectly functional. As you can see in the second photo, the guy I bought these from tried to get the knuckles off the axles by hammering on the axle ends - he put a little lip on the ends so that you can't get a nut on them. You'll need to file or grind down that edge to get the nut on, but the threads are undamaged and the axles are 100% functional. I'll even include two brand-new axle nuts. No shipping, local pick-up in the San Francisco Bay Area only. I'll drive to meet you within reason. Asking $600 for Torsen, axles and driveshaft. UPDATE - SOLD.
