aluminum control arms interchangability

[Harpo]

Are all the years of aluminum control arms interchangeable?

Thanks

I assume you are referring to the rear trailing arms? The '74-'77 trailing arms use a different mechanism for attaching the sway bar drop-link to the arms than '78 & later. '74-77 used a ball & socket fitting with a post on the arm, while the later cars bolted the drop link directly into the arm.

Also, the 930 arms are different than the 911.

Thanks Frankc

That is what I was hoping to hear
