so i got a 73 datsun 620 pickup that has bin sitting for 20 years, but its in pretty good shape except one problem i have. im guessing they hit a curb with the right wheel and the upper control arm and lower control arm are bent. i was wondering does anybody know where i can buy a upper control arm. or since i was planning on swaping out the drum brakes to rotors, has anybody done a full swap from a nissan d21 hardbody or a 720 pickup swap. meaning swap the upper control arm and the lower control arm and the whole wheel hub? pretty much the whole setup? is it possible?
