Just curious. What is your measurement from the far left drivers side edge of your dash to the center of the steering wheel opening. Earlier versions of the Mk4 had the steering wheel opening shifted an 1" or so different from the Mk4 roadster.

Measurement on the Mk4 should be 16 5/8".

Another place to measure for center is from the end of the 2" horizontal frame tube by the hinge mounts to the center of the dash. The hoop is not always symmetrical.
