there are alot of local vendor that should have those. they are not special. just call around to your area suppliers and ask if they have the moog brand. if so have them order up a set(probably not in stock)
I removed the polygraphite bushings and installed replacement rubber bushings from NAPA in the front side of both upper rear trailing arms. I don't know who made them. The fit was a little loose. This may have been caused by the poly bushings being too large or the new ones being too small. I tightened the fit by bending the boss on the trailing arm. The ride was a noticeable improvement. I'm glad I finally did this. Unfortunately, my wheel hop problem remains.
I also replaced my origianls with the good Moog rubber bushings. I only used the poly/graphite on the sway bar and now have the best of both worlds and car does not lean as much on highway exit ramps.
I have installed poly on several vehicles with great results. Usualy they are installed with complete suspension rebuilds and the vehicles performed excellently. I also have them on my '70 conv. and they (along with a sway bar and shock upgrade) make this car handle like a dream and it still has a fairly smooth ride. P.S. I am comparing the handeling of this car to an '80 T.A. dropped an inch, poly all around and it started with the RTS suspension, which was the predecessor to the WS6 suspension.
Many good points were raised and another one is the poly/graphite bushings are harder on the suspension, frame and body because of the stiffness. On my 68 Corvette I wouldn't think of going the poly/graphite route or my 72 GS for that matter, AL.
If you drive the car on the street, I would go with rubber bushings on all the control arms, and poly on the following: 1. Sway bar frame bushings 2. Front stabilizer end links 3. Front shock eyes I did put in all poly control arm bushings. They is WAY too much NVH (noise/Vibration/Harshness) feedback, especially if the roads are less than billiard table smooth. I took them out...lots of rework. Add in Edelbrock IAS shocks, and have a good handling and good riding set up. Just my .02
I did my whole car with polygraphite bushings frame up no problems here no noise feel a firm ride http://www.p-s-t.com/gm.aspx
I put new rubber bushings on my Buick and Dodge about 3 years ago, which both prior to installation really swayed and leaned during turns. With the new bushings it greatly improved that issue. Glad I did it. I first considered Poly until I talked with a friend who put some on his 66 Lemans and he complained that they squeaked even with the lube that came with them. Also, I've heard that they make the ride a little more ridged. I've heard of people putting rubber on the front and poly in back. Why? I don't know.
I have polygraphite in my front (66 Cutlass) and wish I hadn't. I will change them for rubber. They make no noise, but i notice a difference in how it drives, and I don't like it. Also, some think "graphite" in the name means they have graphite in them so they won't squeak. It doesn't mean that at all, in this instance the word "graphite" is used to describe the color, like it is used to describe the color of auto interiors. It has nothing to do with the makeup of the bushing, they are the same as the red ones and all the other colors you may find.
Fact If all the rubber bushings are original, that you are going to replace, and lasted this long why would you change anything other than rubber! The old car front end is worn out from age and use. I guarantee it will ride and handle like a BRAND NEW CAR if you replace all the old bushings and suspension parts! We replace all the suspension parts and bushing to a 86 GN with only 54k miles on it and I can't believe how well the car handles and drives! George
I'm with Bile Bob. From years of experience, rubber in the suspension for complaincy, noise absorbtion, and comfort whilst still retaining the suspension geometry and poly for the sway bars only on the body mounts and end links. The sway bars only move up and down so no binding issues and no hard ride issues. Good luck! Nick
Can JOHNNY JOINTS be installed into Edelbrock lower control arms or any other brands? Curry gets $400 for their control arms with Johnny joints. Many of us could save money by converting ours with the individual joints they sell, if they have ones that fit our arms.
