z240 Posted November 5, 2015 Share Posted November 5, 2015 (edited) The later arms (not exactly sure of the change date, 75 possibly?), are re-enforced in the area around the spindle pin bushing eyes, but otherwise are freely interchangable. Not likely any issue whatso ever for a street car. Might be less likely to deform if the spindle pins need to be removed with "great" force to extract them, that's about it.

JMortensen Posted November 5, 2015 Share Posted November 5, 2015 The 280 arms are built stronger all over. Thicker tubing wall on the inner pivot, I believe the rest of the metal in the arm is thicker as well, reinforced at the outer bushing apparently too. For that reason I'd stick with 280 arms on a heavier 280 car. 280 arms for anything, 240 arms for 240s is the way I'd think about it. That said, control arm failure is not something you come across a lot. Quote Link to comment Share on other sites More sharing options...
