Rear trailing arm/sway bar mod

Can anyone help?
I have a 1967 swb 911 and would like to fit a rear sway bar.
The problem I have, is knowing exactly where on the trailing arms to drill to fit the ball pins.
I know one method, which is to set/fit up the sway bar and then take measurements with drop links fitted.

My trailing arms are off the car and the rest of the car is under restoration.
So, I would like to do this trailing arm/ball pin mod on the bench.

Is there anyone who has a drawing/sketch with measurements of where these holes need to be drilled.
I assuming years ago, the holes for the pins would have all be drilled in the same place????
Maybe, Porsche at the time, would have had a standard set of reference points to go by?
Regards,
Jim.

Why not simply buy a Weltmeister rear anti-roll bar designed to go on the SWB cars?

Indeed, and all bolt-on.

I have a spare swb trailing arm which has the arb pin fitted. I have used this as a template a dozen times, it's currently out on loan for exactly this reason. I can send you some pictures when it returns if that helps. Cheers, Glynn.
