Custom sway bar?
 

Have a vintage O/T GM with a factory front sway bar of only 11/16". Checking if Chevy's bar from the same generation is an interchange (won't be, guaranteed)- there is a 1" bar available to those guys.

Would like to bump my car's bar up to more like 1" but there is zero aftermarket support here. 'Used to be' you could get a custom sway bar made, thicker, patterning off your factory bar.

Anyone know of a company that still does this? Bar is a very simple 'U' with just the 2 bends. Thanks.

'59 Invicta coupe.

Eye-to-eye center dimension is 43".
Bar 'drop' is 7.75" from eye center to center of main straight.

Impala bar I was eyeballing is 39" eye-to-eye.

Carolina sway bar quote : A grand.

There is Sway-A-Way in Chatsworth, CA. Worth a try.
Oldsmobiles usually had bigger front bars, maybe try a '59 88 or 98?

Will try & find a spec.
Found Cadillac's: 47" eye-to-eye.

GM '59-60s are 100% unique underneath (by DIvision), and by a couple shots of the underside of an O-59- it's a different bar by the contour... but will keep hunting. Seems to be my only hope.

Ah, Invicta = Buick. My bad.
55-57 GMs were also division unique. Hard to figure.
My '57 actually has a slightly modified '56 Buick bar for a modest improvement.
I had explored getting a small run of bars made but was a little leary of eating the cost for 10 or 20.
But larger application than just '59/60!

Sent pics and Addco got back to me- they're willing to make a 1" bar to match mine for $415.

That's acceptable to me - anyone have any feedback after using Addco bars?

check out post #669, on page 34, in the 'Lobby' section in the thread 'What did you do you to your Pontiac today'

Bill Bowman1 installed an Addco bar on his 65 Catalina.

He may help


Good Luck

New 1" sway bar came in the other day. Looks very good, matches up well with my factory 5/8"+ bar. Addco was good to work with, tweaked dimensions until I was satisfied. Won't be going on for a while, but :thumbs up:

I got a rear Addco bar for my 73 Chevy truck that was either too narrow or too wide and they made up a new one the correct size!

I'd say if that's in your budget and it's what you want, it's a no brainer. I have an Addco rear bar on my TA. You can see it's not factory, but it fits and functions perfectly.
