Just a little bit of trivia.....you old street rodders an drag race guys and gals will remember....
There is a difference between a 4 link and a 4 bar. Just ask an old streetrodder if he would use a 4 link in his 32 vicky and he would probably say "what the hell for?"
Then ask any drag racer if he would put a 4 bar in his Pro Stocker and he would laugh at you.
If the bars can be adjusted at the hime or bushed end up and down (see the picture that corn posted above) that's a 4 link.
If is like this, it's a 4 bar.
I don't mean to make things more confusing.
