I think they're the exact same rod. You have both in your hands, do some measurements and see if either one is thicker than the other. Whichever is thicker is probably stronger.

 

yeah, specs are same, just dident know if there was a structure difference, but Marty says theyre identical, so since the A6 are in brand new condition im going to shot peen em and mount the vitara slugs on it. Will post pics as soon as i get em together.

 

Tight.
