    Default Dumb sway bar question

    Would a 87 town car REAR sway bar fit a 87 Vic? There is one in the yard and I may go look and see if it has a rear sway bar.

    Yes, bolts right on. Be advised, the skinny bar that comes on civilian cars is pretty much useless. Try to find one off a police package Crown Vic. WagonMan

    I actually tired to get addco to make our bars exactly as factory. They have a custom engineering group. Their presses don't have the tonnage to forge the flat tang as long as ours. For example, their g-body bar has only two small bosses forged flat 6" apart.

    There rear bars are mounted differently...not to the lower arms. They tie up into end links that tie up into the frame....the older frames dont have the proper mount/reinforcement to utilize them.

    Is there any comparison pic or some sort of writeup on the difference. How big of an ordeal it would be to do the newer end link mounting to an older frame?

    If the ends on the addco bar would've been flat instead of vertical, it would probably be easier to find end links of a suitable length and convenient offset to just make a hole in the frame and bolt on. But I guess the welded reinforcements work with factory style vertical end links.

    wonder if that wouldn't work though. Doesn't really need to have that whole tang flat, just needs to be flat where it sits against the bar and a flat spot where the bolt head is. Wonder if they could make the end basically D shaped with two flats for the mount bolts.

    I'm a tool & die guy so I know they don't want to make the investment. The bolt holes are 3.5" apart on our arms. The engineer and I had several back and forth emails. Their tooling isnt modular, so they can't adjust that spread. This is basically why they made brackets to support the #650 bar and called it #324. Here is the PDF they sent me a while back.

    hm, in that case maybe take that same basic design, but attached to angle iron instead of flat for the adapter. If thats the 92-97 bar its probably about the right dimensions already.

    That angle iron idea isnít a bad one. Iíd probably use bolts that run all the way through the control arm with crush sleeves to help prevent the torque of the dork from twisting and fatiguing one side of the control arm.

    Thats the same mounting arrangement the factory bars use, and for that exact reason.

    How to attach the rear bar inner mounts if the car didn't come with a factory bar? I don't think mine has any extra sway bar brackets on the rear axle.
    Some generic u-bolt style solution or weld-on brackets from somewhere? The factory inner mounts are on the bottom side of axle tubes right?

    If a 1997 or older car, if using a rear sway bar secured to the LCA as depicted in the pdf 324 mentioned, one would not want or need axle brackets and bushings like 1998 and newer cars. Those plates to adapt will work if thick enough. GM cars with the strictly LCA mounting came with spacers in the control arms to eliminate collapse with the bolts. If desired to use later style axle mounting, then the end links that are not depicted would need to be used too. If the bar were to be anchored to the axle housing and LCAs, the LCAs would be wrecked when the first suspension movement was made, the bar would move with the axle. I've had a couple GM cars with rear sway bars mounted via just 4 points on lower control arms, it works. One could fab axle mounts using ES bushings and straps and large U-bolts with saddles on the axle. That #650 bar is a full inch diameter.
    No ... I'm not arguing with you ... I'm just explaining why I'm right ...

    Now go ... and whatever you do ... have a safe trip!

    Huh, makes sense. Was kinda wondering whats the point of the non-pivoting end links.
    Well damn, retrofitting a rear bar won't require fabrication really, using the factory style lca mounting. And I'd rather do it with angle iron and crush sleeves like mentioned.

    Cool, I can use a drill and a saw, but not really a welder so I'm even more inclined to get a rear bar now.
