I just picked up an 89 TBird SC and need to replace the Rear Upper Control Arms and the knuckle bushings for both as well, anyone know where I can order these parts?

Thanks for the info Grog6, but I checked and Rock Auto does not have the rear upper control arms from what I can tell, any other suggestions? Thanks

You can't buy arms.

You can buy bushings.

After googling a link for you, I came to this.

Public Service Announcement: Rear Upper Control Arm to...

An issue has recently come to light that I felt warranted documenting and spreading the word about. It seems that in addition to the original design of the rear upper control arm to subframe bushings there is also a flawed design that's been infiltrating the market over the past few years...

Read thru that.
If you search, you might find a thread that will tell you the easy way to do them.

Read that PSA very, VERY carefully.

Then, order some poly (for street usage) or delrin (which is what all the Big Boys use!) spindle bushings; I'd go Prothane black instead of my ES blacks since Prothane impregnates the poly with graphite, but you do you. (I have Energy Suspension because I didn't know that. They don't squeak, but eh.)

For the inner LCA bushings, poly or delrin. Delrin again is what the big boys run; poly can take a set it seems.

Well you can buy tubular UCAs from SCP if you have an arm and leg to spare.

Because I have a detailed list of my ongoing build, I'll share. I'm posting from my phone right now, so the list is zoomed in a bit. I'd advise you replace the toe compensators as well, but that could be done later as it's an easy access item unlike removing the knuckle for everything else.

Anyway, you are looking for the parts listed in red. My parts here are a mix of OE spec, prothane, and polyurethane. The arm itself isn't available for sale unless you go with the SCP unit that costs just a notch below your first born.
