Default Converting early A arm to later

I really hated dealing with the sway bar end link "blocks" of the steel control arms. Seems I'm always doing something that requires dissasmbly and assembly which is a pita. Also the M030 bar doesn't fit unless you drill out the rubber 3/4". So I had a clunking in the front end forever and think that's my source. So here's my conversion to late model (post 85.5).

My arms are boxed so very strong and balljoint replacement is cheap and easy. I borrowed an '86 arm to layout the end link location

Pretty close but this is full droop. Looks like a successful modification

Is it normal for a street (early 83) with steel arms to have problems with the stock sway bar? Perhaps this is only necessary with the heavier bars. I have added poly blocks to mine, replaced the arms with new ones, and new ball joints, but haven't gone with the boxing mod on the edges..Good idea for a stiffer lower arm..any further suggestions for a street car??

If the rubber is good in the end links I wouldn't change a thing(street car). I did this because mine were shot and I am always taking them down for one reason or another, which is a pain to install with those small bolts.

Are you wishbones not Parallel with the ground and sat at an angle as the car's lowered ?


I know you can get / adapt a longer rod Balljoint to cure this, I'm just wondering how your steel arms and the stock balljoint length does? and also do you think if a metal extension bar was made to fit inbetween the stub axle and wishbone balljoint it would be ok, as opposed to changing the ball joint to a longer version?


(I have fitted aluminium short wishbones with new Balljoints but they sit at an angle) it's street / Sprint use.
