I'm having trouble finding what bushings are in the rear of our cars.

I still have all the original bushings in my car. Why do you want to change them?

I'm hearing what sounds like something rubber that is loose when I go over bumps coming from the rear. I had the exhaust checked and that is free and clear. the air shocks are not leaking and seem to work fine.

Sway bar end links? Make sure the shocks aren't leaking fluid and the shock mounts, top and bottom.

They don't make a front bar for the 95, only 97-99 which takes a 2018.  The rear bar for a 95-96 is a 419 (7/8").  The 2419 is the rear bar for a 71-78 Riviera according to the catalog.

The end links are new. I don't think the shocks are leaking but I will check again when I have my front GM strut mounts installed and get rid of the defective Gabriel mounts as we spoke about. It's probably my oe shock mount(s). Thanks Larry.

My passenger rear has been clunking too. I'm pretty sure I replaced the shock mounts when I took the ranchos off a few years ago, have only put a few thousand miles on the car since. The mounts are torqued down right. The end links are fine, I had a look at them when I tried installing AA's RP end links.

I have not had good luck with aftermarket mounts, that's why I'm going to try original GM ones.

I installed new Moogs in 2016.

Moog used to be top notch stuff, but I'm hearing that they aren't what they used to be anymore.

I looked at the top of my rear passenger shock mount and couldn't see anything wrong with it. I whacked the top of the shock with a rubber mallet and twisted it with vice grips. It was fine as far as I can tell.

Larry,
Do you like the 2018 and can/should I run it without doing anything to the rear?

Yes, the 2018, and the strut tower brace transformed the handling of my car. You can run it with the stock rear bar. I upgraded both. 2015 is the rear bar.

I am going to order the sway bars from Addco, no one stocks them anymore. The rear is 12+ weeks out but that is fine. The STB is a unicorn, I gave up on it.

It is possible to make your own STB. All you need is some thick walled tubing and end plates. Know anyone with a plasma cutter and a welder?

My job has that if you could give me some dimensions or possibly a drawing. I could also have the office do something on CAD but we don't have a CNC machine. We do have a welding department when we make fire doors.

All you need to do is build it out of cardboard and a stick. Tape it together and measure it. You can get an idea by looking at the pictures in the STB thread.
