trailing arms: Goodmark vs. ECE vs. OEM

[69Tom]

After doing some research on here, I'm beginning to think my trailing arms are a little too rusty to keep using.

Therefore, I'm looking for a set of new (to me) ones.

I was considering pulling the trigger on a pair of the ECE arms. However, people say not to used boxed arms, as they don't flex enough. Not sure how true this is or not.

If it's true, that leave me with a) finding a clean set of OEM arms, or b) buying some Goodmark repops on RockAuto.

Any opinions here? I'm a little confused based on all I've read. At the end of the day, I'm a pretty original guy so I guess maybe I should go with a nice set of OEM arms if I can find some nice ones close by.

Thanks.
