Question about borgeson joint

[65 drop top]

I just bought a 3/4-36 borgeson joint to install on the DSE rack on my AME chassis. The borgeson joint seems to fit the rack kind of loose, you can feel it wiggle around just a bit. I know when I tighten down the set screw it will feel tight, but seems like I don’t want to rely on a set screw for good spline engagement. Any one else experience this, or is this just normal? On my other car with stock steering box, that borgeson joint fits snugly.
