Yes, the spline teeth sides are parallel, about .270" wide. Lots of good info here. I just did a trial cut, a 3/8 carbide end mill cuts it easily.
The spline end diameter is 1.090". The area I need to spline is 1.040" diameter, results in the .025 reduction in spline height, not enough to worry about.
The shaft diameter is very consistent, with the centre bearing diameter at 1.100"
With a shaft length of 48" I'm not sure how much I need to worry about whip.
In the mean time I have turned down an NOS 6/10 spline adapter to fit the cut down '34 tubular drive shaft. I will take it to a driveline shop for aligning and weld up.
Looking forward to getting the chassis on rubber!
