Was doing some research on PY and the net for rear sway bar parts and came across a reproduction bushing being made by our friends over at NastyZ28. These are a match for the 5/8 bar, lower bushing Part #3983071

Thanks RamAirpwr! What are they charging for a set?

What are they made from? Hopefully OEM type rubber?

I have a bunch of NOS bushings, and they all seem to have a flat area? Is that the correct shape?

[Norwood]

The bushings that are on the ends of the bar would have flats. The bushings that go where the links are would be round.

[Judge273]

Do the link bushings look like that?

[Norwood]

Yes, the link has the Permanent bushing in the top and that bushing on the bottom. There is a different bushing for each size sway bar.

Good to know! Repops are a lot different then.

Unless I am missing something, I believe you may be mistaken;
It sounds like sway bar bushings you mentioned which do have a flat, are for the ends, not the links - these are for the links.



It sounds like you're talking about part #7, but this is the bushing for the link - which isn't actually shown in this diagram, but is sandwiched in between the link (#1), and the link cap (#9).

It is worth noting that the sway bar end links did change;
I am unsure if the revised links used a flat on the top.

As Norwood mentioned, there is a different bushing for each sway bar size.

I actually started following this thread yesterday, because up until now, I was unaware of a bushing made for this - I had understood that most people just made one out of rad hose...

Your Trans Am should have a 7/8" (0.875") rear bar;
This is for a Formula, which came with a 5/8" (0.625") rear bar.

@ RamAirPwr;

Again, do you know what is being asked for a set?

[unruhjonny]

here is a link for a reproduction rear sway bar end link - which clearly shows the rounded shape on both ends:

Here are two different sizes that I found from the same vendor:

Here is a good pic I just stole from Bruce. It shows the round bushing and the one with the flat that is on the sway bar end under the spring plate

[unruhjonny]

well bummer.
It looks like this thread might have been all for nothing.

I emailed Tom, and got this reply:

Hi Jonathan,
I am sorry but I only have the 11/16 and 9/16 diameter at this time. What demand do you anticipate for the 5/8 inch bushing? It could be produced in the future if there is a big enough need.
Thanks for you interest.
Tom

I'm gonna take a leap of faith and say the 9/16 will be interchangeable with the 5/8 (formula) and the 11/16 with the 7/8 (T/A)
What do you guys think?

Thanks for the schematic. This is a breakout of part numbers I gathered from other threads and my own research

Formula 5/8 bar
Image #7 GM Part #480912 or Energy Suspension Part #9.5104G
Image #1 GM Part #3982298 (link w/bushing) For the bushing only, use Energy Suspension Part # 9.8140G (this is the bushing on the top of the link)
Image #9 GM Part #3983071 or repop from Tom

T/A 7/8 bar
Image #7 GM Part #482333
Image #1 GM Part #3982298 (link w/bushing) Don't have a cross reference for Energy Suspension
Image #9 GM Part # 3986486 or repop from Tom

Hope this helps!

I bought my lower drop link replacement bushings for my small diameter rear sway bar from PST (performance suspension technology).

They are not made from OEM rubber, and have a little larger diameter on the outer edges. You can see that in the pic I attached. I figured this was the best I could find so that is what was installed. These were much better than my originals:

I'd buy two sets of those in 5/8".

(Jonny, BTW many '70 T/As came from the factory with a 5/8" rear bar, even though the literature said they should be 7/8").

[unruhjonny]

/\ yeah, I have read that.
It seems to me that often owners look to correct factory mistakes - which played into my reply.

I told him that if he did a run, I'd buy two sets as well.

I also encouraged him to check out this discussion.

[455hota]

If we are looking for potential buyers of the correct bushing for the 5/8 bar, I will buy a set.
