Control arm mount question

[Firefighter Z]

Just wondering if the Upper Control Arm/ Assembly from a Stock Camaro is diffrent froma Z28?
The front upper control arm mount is rusted through on my z28 so i found replacements but there 2 codes... A P40 code and the 1LE

Is there a diffrence?

Explain what you mean by upper control arm. Our cars have lower control arms that attach under the axle tubes to the sub frame of the car, a torque arm that attaches from the center of the diff to the tailshaft of the transmission, and a panhard bar that attaches the rear of the driver side of the axle tube to the passenger side rear sub frame. :hmm: I believe 1LE is an option code for upgraded factory suspension but I don't know what's different. Parts wise V6-Z28-SS suspension parts will all have the same deminsions but possibly different bushings. The front TA mount will be different on an M6 and A4.

Ok, now I feel dumb I thought you were talking about the front mounting point of the rear suspension!:embarassed: I'd go with the 1LE,
IDK why it wouldn't fit.

Well I got the assemblys. The F41, I guess its an all around part and the 1LE's came on the special ordered.

Now what it the rubber part that sits between the fender well andcontrol arm assembly?
Is it some sort of bearing?

I'm guessing your talking about the bushing, if so it's not a bearing. I tried to look it up on gm parts direct but the picture isn't loading.:(

Ya I cant find that part anywhere.. Does it have some sorta weird name to it?

Right now I'm dealing with Installing new Lower Ball Joints, but my China tool isnt working to well.. I've used adapters to no luck... I really dont wanna pull the lower A- arms off.
