I managed to bend the driver side lower control arm on my 84 300zx n/a. Is there a way I can get this thing straightened, or should I buy a new one? If anyone has one cheap let me know. Thanks.

 

check it out. That arm can't be bent back, but on the bright side of things there should be a plethora of junkyards just icthin' to sell you one.... Oh, you might go ahead and replace the balljoint in the used arm.(the are usually no good off the yard)
