8 3/4 axles from truck/van/ or C-body to use for narrowed A-body project

Looking for axle shafts from 8 3/4 out of a truck, van, or C-body that I can cut and respline for a narrowed A-body Dart project. If you have anything sitting around let me know.
if you do this make sure there is enough "beef" at the end of the axle to be re-splined. not all of the axles you listed are the same. some taper down at the end. Its a hit and miss deal trying to find the correct ones
