Want to buy right rear axle shaft for 90 Formula 350 with disk brake rear end. Any members have one? Thanks for your support.

 

Watch the classifieds on this site.

I doubt you'll have much luck buying that; nobody in his right mind is going to bust up a highly desirable rear end like that, just to sell one axle.

But: the axles are the same left and right; and they're also the same in those years whether drum or disk AFAIK. The only difference would be the outer diameter of the wheel flange; the disk ones have to be small enough to fit inside the rotor. So, go to the junkyard, and look for a 90-92 6-cyl Camaro or Firebird, and get the whole rear, that's probably the cheapest way to get one axle. Just make sure that your rotors fit over the flange of the axles.

It might even have better gears than your V8 car came with.
