Where can I get the rear swaybar endlinks for a 71-72 B-Body rear swaybar? The distance between the bar end and the bushing end is 2.5" and the overall distance from the bar to the end of the stud is 5". It is a 1" bar.

Are there any other models/years of Mopars that use a similar design?

Where do you guys get the bushings for the frame brackets and the bar ends of the endlinks?

I have included picts of the parts in question.

Any help will be greatly appreciated!

Is there anyone that can help me? Someone must have had to replace the factory endlinks on a 71-72 RR rear swaybar.

Please Help! I am trying to get the car rolling again and I need to get the bar under with the rearend.

Do you need the whole endlink, steel and all? or just the bushings? The bushings should be easy to find, mine looked pretty universal. If you need the whole thing and cant find some proper stuff you might be fabricating something, which shouldn't be too hard. I got lucky with mine.

This might not help you, but when i bought my 72 Roadrunner it came with the (original) bar in the trunk and a bag ov ancient Mopar performance (Direct Connection? stock replacement anyways) endlinks with it. But there was no way to attach them. The endlink itself just kinda came to a stub where it attaches to the bar and we had to weld it to the bushing bracket. I was pretty concerned about doing that, but there was no other way (the guy i had do it is a suspension expert and knows his Mopars). We welded the endlinks to the bar, then welded some brackets onto the frame because there were none there and we couldn't find anything from a donor car anywhere at the time.

Anyways, despite my concerns about welding the bracket with the rubber bushing still inside and maybe even the whole idea ov the set-up its held solid and worked really well for years. I drive my car hard too (and have broken a rear sway bar in my 96GT) so i'm positive it would have broken by now if there was a problem.

I purchased a kit from autozone that was supposed to be a direct replacement. We ended up using the old bolt and the new bushings (red) until I can switch in the black ones. Rock Auto also had a front sway link, I'll bet it's the same as the back? Maybe someone can verify.

Thanks guys for the info! The biggest problem I have is that the link bolts themselves are rusted beyond reuse. I have a set of usable endlinks from what I believe to be a rear bar from a 75-79 B-Body. However, they are 1/2" longer than the ones for my RR. The only thing I can see it doing is raising the bar up an extra 1/2".
Will this extra length negatively affect my handling or will it not cause a problem?

The bracket that attaches the bolt to the bar will be an easy enough fix. I am going to drill out the spotwelds to remove the bracket from the bar. Then I will install split bushings on the bar and bolt the brackets back together over the bushings.

When installed, this extra length to the stand-off stud for the later b-body rear bar, would actually lower the position of the bar that ½” in relation to the ground on the 72’s. I’m currently running a later rear bar with the longer stand-offs on my 72’ without any adverse effects.
Still hoping to locate the correct 72’ Dana b-body rear bar at some point down the road.
When these cars were new, the only way to service these brackets was to replace the entire bar assembly, eventually repair kits became available to service the stand-offs which tended to break under certain load conditions. These repair kits used a single bolt clamp arraignment around the bar isolator.

If the endlinks you have are longer, I don't see that as a problem. If the endlinks are shorter, you MAY have a problem with intereference between the bar and the diff pumpkin (I'm assuming you have a 8-3/4). It's worse with the Dana.

No.

If you do that, you might as well cut one end of the new endlink off, so the the remainder is approximately the size of the existing rusted endlink piece. Then weld the new piece on the upper half of the split bushing bracket.

Sorry I don't have pics of what mine looks like, but 72RoadRunnerGTX might have some somewhere here, or you might try somewhere at www.roadrunnernest.com.

Good luck, and post some pics here of what you end up with when you get it done. I'd be interested in how it turns out.
