Default Is my control arm bent?

So my (previously wrecked) c5 has been getting a suspension rebuild, which has included some vansteel delrin bushings. Went to go install the front upper control arms, and the drivers side is waaaay off.



This a sign that the arm is bent? If I lay it on the floor it rocks as though the rear-ward arm is bent upwards, and I can definitely see the bushings arent on the same plane. Just want to get yalls opinions before I spend money on another one.

The car was wrecked when I bought it. Went offroad at highway speeds, took out the front cradle and spring so I wouldnt be surprised if it was hit hard enough to bend it.

Can't tell just by looking, no apparent bend compared to the arm on my car.

Can definitely see the bolt holes are on a different plane. And i can "rock" the control arm laying on the ground by pushing down where the balljoint goes.

Im fairly certain its bent

Get yourself a new arm then, or a good used one from salvage.

Take the other side out too and compare them. Well, if you end up having both of them out, might as well get replacements.

The factory a-arm rubber bushings allowed more adjustment to install the arms but now the Delrin bushings have no slop so that's why things don't fit and it does look like the arm is bent.

Too many variables before adding the delrin bushings. You cannot evaluate a casting with secondary machining by laying it on a flat surface. Cast surfaces are not control the same way as bores for ball joints and bushings. Lacking a drawing, you would have to have a known good part (bare) to measure on a granite table with setup blocks to be certain....then compare the suspect bad part.

How did it unbolt aligned with the mounts if it's "bent" now?
if you rotate each bushing 180 one at a time does the misalignment change places or stay? can you remove the bushings and insert a dowel through both?
