Early rear anti-sway bar link modification

[Joe911]

Looking to the BBS before I cut and weld. I have a 22mm Weltmeister rear anti-sway bar with adjustable link that I am installing on a 1969 911S with the original steel arms. The stock bars snap onto a ball on the end of a pin arrangement at the C-arm via a shackle or link, sort of like carburetor linkage. It looks like the later cars and the Weltmeister links are designed to slide over a pin or stud (no ball). The Weltmeister links have a rod end/spherical bearing on each end of the link for adjustment.

As this must be a common modification/update for those of you with early 911s – how have you done this? It does not look like the ball/pin would press out of the early C-arm. I was thinking about cutting and welding (grafting) the early upper end of the link onto the threaded link. It would still be adjustable at the bottom – and as it would be in tension and compression – strength should not be a significant problem.

Any help is appreciated. Speaking of help – many thanks to all those who have posted rebuild info as you have done projects.... or just seem to know it all (i.e., Warren). I am generally a tacit daily reader and have used information from the web site to disassemble, clean/paint, rebuild – except engine and trans on this old car – learning as I go. Also thanks to Wayne and all the folks at Pelican Parts!

PS - Anyone going to the Porsche Rennsport Reunion at Lime Rock? Anyone driving up from the south – although I think I will rent a van and bring my sons rather than take either of the Porsches.

The Weltmeister rear bars I'm familiar with have drop links that bolt to the spring place where one of the 'eccentric' bolts normally is. No fabrication/drilling/cutting is required. You may be missing some of the hardware for the bar!

The Weltmeister links have a rod end/spherical bearing on each end of the link for adjustment.

The rear sway bar link only has a single spherical bearing on its upper end. The lower end that attaches to the sway bar is a rubber bushing.

As Chris Campbell said, seems like you're missing the WM eccentric mounting bolt that replaces the factory-installed eccentric. The Weltmeister piece has a 5/16" female thread. The upper sway bar link attaches to this via a 5/16" allen head bolt that goes through the upper rod bearing then threads into this opening. You'll notice the spherical bearing has a 3/8" I.D. WM supplies spacer collars that allow the smaller dia. bolt to fit into the bearing and also allows greater bearing angularity than without.

I've always thought the 5/16" bolt a little puny for this application. In addition, I think the supplied spherical bearing is on the low end of avail. materials. Anybody have any "experiences" with this size bolt?

Joe,

Is the Weltmeister bar you have a new kit, or a used bar off another car? It sounds like you have the bar for SC and later cars where the spherical rod-end would bolt to the 'eyelet' on the aluminum control arm.
