Braad8, not that big of a deal, just did this yesterday on a big SOTA and it is totally enclosed in a cabinet w a top. Contrary to Fleib, adjusted cue height with arm on table in the cabinet!!! Be brave. Most definitely .035" for the cue height.

Agreed with Fleib it is a PITA. Very correct, the access hole is not perpendicular However, this can be done. Fish around with the .035. it is a very small hex wrench. Try to change the angle of approach with the wench until you feel the wrench lock into the bolt head. Put the long arm into the port. Twist the short arm. I have never overtightened for fear of stripping. You are dealing with vintage metal and plastic here, don't get too ham fisted.
When you do get it set up correctly it may seem a little weird at first, with the cue in the full up position it appears that the entire cartridge will not clear the LP until you move the arm towards the platten and it hits the raising bump thus clearing the LP.
If it is stripped you could have arrived at destination F****D! Machine Shop may have an idea? Drill it out? Could screw it up more trying to MgGyver. John at Audio Origami should be able to figure it out or at least give you some ideas. Check his website forum.
