Joe, after having problems with the factory, 21 spline inputs failing, back in 97', I sent one to a lab to have it checked out....
It costs me about $100.00 to have it complety checked out.
As i remember, the closest american alloy was 1050, or 1051.
This is a tool steel, and is case hardened by adding carbon.
I still have the results some where.....
