Eibach Rear Swaybar mounting help needed
I am finishing up assembly of my 1975 after rust repair and ran into a snag. I have the Eibach swaybars and they say to “remove” the ball swaybar mount to install the later Carrera style drop links. They dont tell you how though.
So I need to remove the ball you see in the pics below, and install something like the stud mount in the last pic. I am not sure these are removable though. Esp after 50 years. Any thoughts on if this is possible, or a better/different solution? Trying to avoid sourcing the later style trailing arms and swapping them over. I had thought about cutting off the ball, and just tapping the remaining part for the droplink. Pic’s from eBay add’s What I have on my arms….  What I need to have…the rust stud at the very bottom of the pic.

The Eibach bars are not listed for your car. They start at 1978 and up.

My 911 is a '75 as well.
The ball on alu trailing arms is not intended to be removable. There are a number of ways to install an adjustable drop link to control arms with a ball. I fabbed some up years ago:

Don't try to remove the balls, I don't think it will work. I used a huge pipe wrench on mine from a 1977 and didn't get them to move one bit, totally screwed up the ball surface because I had great bite into the steel.... I think they are placed into the arms when they are cast.
You could try to cut them off and then drill and tap, however I'd do that in a mill to ensure you don't drift off into the aluminium. Because of the amount of work and risk I'd recommend to get some sway bars that attached to the spring plates, or swap the arms with somebody that has the stud mount. Cheers, Lukas
