Default WTF? Sway bar mounts

I have a Charlie Bar rear sway bar for a 911 that I need to put on. The mounting bracket is solid billet AL with two 8mm holes drilled 57mm on center. When I went to mount it almost 3 mos ago, I recall the left side mounting correctly and the right side (were it seems the mount had bottomed out) did not. No biggie, I figured, I really need the Wevo mounts anyway with a large sway.

Got the Wevos today. The holes in the Wevos don't match the brackets on the bar. WTF? The Wevo holes are drilled 65mm on center. The bracket is 57mm. Coincidentally, the distance from the from the OUTSIDE of the holes in the bracket is 65mm (8mm holes). Hmmm...

So question is - are the holes in the factory mounts 57mm or 65mm on center? Are the Wevo mounts I have defects or do I have some odd sway bar? Like I said, I seem to recall the sway bar bracket mounting correctly, but it was very late the night before a DE 3 mos ago.

Anyone have a car under the knife they can check? For the metric impaired, 57mm ~ 2 1/4", 65mm ~ 2 9/16"

Fuch. Mine too. I looked when I went back out and realized I could remove the sway bar mounts with the car on the ground. I did and measured - 65mm. That means I have to go with the odd sway bar and my memory is crap for thinking these bolted up on one side.

The only thing I can figure is these bars came off an early 911. I know this because they had a ball cup style drop link for the early style trailing arms. The early cars must have smaller 57mm sway bar mounts? Granted, it's a purely academic question at this point.

All the 911's until the 911SC in '78 had the cup-style drop links.

Really? I thought the cup style stopped with the AL trailing arms that came along in 74.

Well, a little searching shows that sway bar brackets from 69-77 are different than brackets from 78-89. Dammit.

Learn from my mistakes - know the differences in cars when you buy used sways. First I had to find a solution for the damn ball cup thing, now this. :XX My whole process of trying to mount this damn bar should be posted in the "Fail" thread.

Answer my own question - apparently early AL arms did have the ball thing:

I see the ball thing I think you're pointing to, but what does that have to do with the sway bar mounts? I thought the mounts you were talking about are the ones that mount the body of the bar to the body of the car, not the ends to the frame.

And I found your problem, Chris. You have TWO LEFT HANDS! I don't know how we all got this far without realizing that.

I'll type slow because I know you don't follow stuff so fast:

- I bought early car sway bars.
- The first problem I noticed was the drop links were for the "ball" style, not the "bolt in" style
- Early cars also had different body mounts (57mm vs. the 65mm or SCs and up).
- Thus, had I known then what I know now, seeing the ball cup drop link would have told me that the body mounts wouldn't fit.
