Can’t find replacement axle shaft for my 73 F100. Does anyone know a part # or anything that could help?

I wonder if Rock Auto or LMC Truck could have the part.

May be challenging to find new, may try salvage yards although the age may be an issue as well. Otherwise perhaps some of the race suppliers like Summit

Summit shows a cut to fit for a 31 spline 9”. $226.99 each.
