Steering column and intermediate shaft, which I have already made and had crack tested etc now has to ALL be re made as no steering components are to be welded unless factory welded or if there is no other practical solution say the certification people.

So I found a collapsable column from a 2003 Subaru the right length and splines for the steering wheel, Woodwood have a universal that will fit that, which is metric GM Vega. A few visits to the car wreckers to look for suitable 3/4" minimum diameter steel shaft to make the intermediate shaft and have it splined to suit the 0.750" x 20 Vega universal etc.

I have looked at torsion bars on 4x4 vehicles but they would be tough spring steel and drag links on similar vehicles etc as I assume they would use a suitable quality material in steering components but I still dont really know what the grade material is.

Advice on suitable high quality material that can be machined for splines would be appreciated.
