Splined shafting?

Does anyone know a supplier to get splined shafting and splined collars. I am going to be building a cantilever front suspension and I googled the hell out ofit and had no luck. Really looking for just a long piece of shaft that I could cut down and the collars have the opposite splined shafting so it would slip on and I could build the canti arms off of that. Thanks

McMaster-Carr?

What about using a old torsion bar? Maybe you could just key it or dowel it? Maybe theres one thats already splined?

What about the splined steering shaft from Borgeson? It comes in different materials and lenghts, just an after thought.

If anyone remembers who owns it there was that red fullsize on the cover of streetrucks this year with a setup like that in the front. I think he's posted pics on here during the build-up. Got the issue at home or I'd look for you. I'll check tonight if I get a chance.

The guys at RCVperformance.com can make you splined material to your specs as well as broached bungs to build from. Their prices are very reasonable, talk to Sean Carlini.
