Front suspension issue
2_Darts, what is this with the Anti-Roll Bar? Is that like a sway bar?
Yes. A lot of people use the terms interchangeably. What the bar actually does is reduce body roll when cornering, making the car corner in a more flat attitude.
The tabs on your LCA will allow you to use a anti-roll bar as the factory intended. Most aftermarket sellers offer L-shaped tabs or brackets that attach suspension using the lower shock bolt. Not sturdy, no good.
Since the lower shock bolts are farther apart than the LCA mounted tabs, anti-roll bars may be in one of two lengths. If you go looking for a new anti-roll bar, make sure it is made to fit the factory, and not the aftermarket, set up.
Excepting the 340 and Formula S cars, I have seen very few cars in salvage yards with LCA like you have. That's why I suggested you take care of the ones you have.
Obviously, not having the bar installed does not make the car undriveable. With the bar properly connected to the body and suspension, roll during cornering is reduced. The trade-off is harsher ride when the car encounters a large amplitude bump or a series of bumps. For me, I'm not driving across a freshly plowed field (A Citroen 2CV does this well), and I'm slowing down for the craters in the streets here at the Edge of the World.
