As you've figured out, with the closed knuckle axle, the adjustable drag link is about the only option as a raised steering arm isn't available. I used the same drag link as you are using on my 69 K20 and it definitely fit differently than yours.

I'm assuming your arm has a taper to the hole. I can look at my drag ling end tonight as I have one of those pulled presently but I'm just certain it has a taper to it.

If it doesn't have a taper, I'd be very reluctant to put alot of torque to it - something is wrong. Maybe give the manufacturer of the drag link a call.
