Another rear sway bar question

[3stewartS]

I have a broken rear sway bar mount (imagine that) on my '76 911. I have decided to go with the WEVO consoles but here's the rub: I need to update the bracket and bushings. I have a 19 mm sway bar, the updated bushings are for a 18 mm bar.
I also have in my spare parts a later 18 mm bar and brackets (from an SC) so I'm good to go for brackets. My question is which bushings do I need to fit the bar to the consoles. I know which ones will fit the bar to the drop links.
Any input is appreciated. I'll take pictures if needed.

So here's a pic of the worn 19mm bushing and the "later style" 18mm bushing. note the shape at the bottom of the later. That's what I believe to be the difference.
Am I overthinking this?

Thanks Ronnie, I had already read your post. Good info there for sure.
Still, my concern lies with which bushings to use. I already have brackets that will work. If I buy bushings for the later model to fit the consoles and brackets, They are for the 18mm sway bar. Can I simply install those on my 19mm bar and clamp them down?

You need to buy bushings specific to the diameter of the bar you're using (the bracket size remains constant)... If you use a 18mm bushing on a 19mm bar you're likely to get binding and noise.

I am now wondering if the sway bar on my car is original.
Is a 19mm rear sway bar standard for a 76 911?
The front bar is 20mm
My spec book says 16mm ft and no size is given for rear
except turbo and carrera 18mm
the bar is silver (mostly rust colored)
I can find no identifying vendor code on the bar.

Hard to say... But I'm pretty sure Porsche spec'ed a larger rear swaybar than on the front as "oversteer is preferred"

So It seems a bushing is not available to fit my 19mm sway bar to a WEVO mount.
I guess I'll have to fabricate/modify.
