Part Number look Up Question

Can someone help me with a part number application.Control arm #3408934 Thanks for any help !!

That's not list in the Passenger car 70-71 parts book

Where are you finding the part number? If it's on the part itself, it often isn't the part number.

Someone had hand written it on a tag.I didn't find anything either.Pretty sure it's an A body arm.These would have the "VL" stamped on them correct? And is there a difference between 1970-2 lower arms and 1973 up arms? I know the spindle size of something changed,

it might suppose to be 3402934 but that would be a cuda challenger lower arm

post a picture

I don't have a picture yet,but is there any difference between 1970-2 lower control arms and 1973-6 arms? Or just a different/supersede part number? I think they used larger spindles or brakes on '73 and up,but did the lower arms change at all?

Sway bar brackets are welded in different locations. 67-72 is out near end. 73-76 is in middle of LCA.


All performance A-bodies 340, 360, 383, 440 got front sway bars.

Other than that, I think? there is a date code stamped on them?
