Thorens 160MKII BC Grace 707 + F9????

What a shame, oh well, you certainly didn't spend any time with your head in your hands.

What flexibility do you have when changing arms on a TD160?

707 is 225mm spindle to post, the acos lustre gst-801 is also 225mm, 15mm overhang, removable headshell, magnetics used for tracking force and anti-skate, and super smooth VTA while playing. you would love it I am sure.

I'm on vacation so I cannot pull the manual, anybody know the diameter of the hole to mount it? The bottom is a thick heavy 

My friend and I got lucky, his azimuth was good as normally mounted.

old days, you needed to improvise a strip of thin plastic or paper on one side between top of cartridge and bottom of headshell until correct, total pita.

I found this

"Just realized azimuth is adjustable on the 707! Fine-tuned it and it has made a bit of a difference, especially at the inner grooves. Unfortunately the set screw at the rear of the headshell, underneath, is a bit of a pain to access. But what an arm!"

however, another discussion says it is not adjustable and to be careful not to overtighten that screw or the plastic headshell will crack. glue was found, and it might have been factory original glue or subsequent repair glue.

I haven't seen the manual, surely IF it was a feature, it would be mentioned.

The Micro-Seiki 505 headshell fitting is adjustable, access with simple small flat screwdriver from the side while mounted. Wonderful, ought to be an industry standard.

micro seiki 505 is also 225mm spindle to post, a wonderful arm, reasonable price
