What diameter is a stock 93 Touring rear sway bar?
 

I'm trying to buy bushings for my 93 rear sway bar.

I bought a bunch of other bushings through Powerflex and since they only listed one size for the rear sway, I ordered those too (18mm).

When I went to put them on, they were quite a bit too big. I took a caliper and measured my swaybar and it seems to be ~17mm.

Now when I search for replacements, I found Energy Suspension bushings that say they're 16mm!..

So what SHOULD my car have from the factory? The bar and rubber mounts look really old, I doubt they've been changed. Help?

Thanks.

Can't comment on the Touring specifically, but some of the early cars were around 17, mid 90s they went to 13.8 and later, there's another diameter again.

93 were 17.3mm. Energy Suspension offers a 17.5mm but it won't fit because there is too much material and it won't bolt up to the car. You can try the 17mm. It might be tight but if the bar is a bit worn from use anyway it might work.
