worth the effort and expense? probably not.
I will be doing the mod soon on my '84 though since I have a spare set of aluminum arms lying around, and the ball joint kit is cheap.
The steel arms are very cheap to replace, and once you have replaced the ball joints in the steel arms once (drill rivets and replace with bolts) it is VERY easy to do again.
There are proponents of both style control arms. Both styles have their good points... I think that in the end this comes down to preference. I do like the looks of the aluminum arms though
