Hey csprague, any news on that swaybar that i want?

You've got mail.

Alright then, it appears that ADDCO does make a rear sway bar for the 92-99 Bonneville's, and the catalog has been sitting here on my desk the entire time. Anyways I can get it for people if they are interested.

I can get it for $190 shipped to your door, so if anyone is interested, let me know.

The bar is 7/8 inch thick.
This includes the urethane bushings as well.

Yes it is a perfect bolt on and the car feels like a totally different animal with the brace installed. The car tracks much more precicely now and I can take corners at a slighter greater speed, 5 or so mph, with confidence.

Here's something I dug up that may help too:

Installing a Buick STB

By Mike DeQuardo


--------------------------------------------------------------------------------
GP rear strut tower bar (via Buick Regal OEM front shock tower bar P/N 12456148, (GM refers to it as an 'f-bar kit') Total installed price; $8.

The bar has two holes on each end. I simply 'reamed' out one on each end (on the side closest to me) with a 1/2 inch drill bit. Not very scientific and quite sloppy to be honest. I just kept reaming it out until I could slip the bar over the two-strut tower mounting bolts easily. Then I simply removed the two nuts from those bolts with a 15mm open-ended wrench (ratcheting version would be preferable but not necessary), placed the bar on, and snugged up the nuts tight. 20 minute job.

That's a GP rear STB installed on the REAR of the Buick/Bon, or the front?

That's whats I was trying to figure out too! The directions are for the front bar, but it sounds like he's installing it on the rear of a GP though? :? The bar is FROM a Buick not on a Buick! :roll: I've never tried it since I already have a front factory bar! But the earlier Bonnevilles (Prior to 92) did not have one! :cry:

If I could get one for cheap, I'd like to install one on the rear......don't know how much difference it would make until I try. I drive like Drifter, just not as often. Just a thought....

Hmmmmm....... :idea:

I don't think you can install a rear brace in the bonne's at least not in my 89 I looked around trying to figure it out and could not.

My 1995 se Bonneville has a big metal structural base that is spot welded to the rear strut towers. As for a rear sway bar one can be made for a 89 if you are serious. I can have one made for you if you want.

Hey this is my 666 post I am sure da rat would like that.
