What is that pin called and where should I look for a replacement???

 

Are you talking about the bolt that joins the shock to the lower control arm?

 

Thats the one Ps-> Are those "lower control arms" the same as the "camber kits" I see on ebay?? I also see them on some civics when I drive behind them.

 

lower control arms are not camber kits. camber kits are the upper control arm.

Yup it's a lower control arm bolt you're looking for... i'd just grab some from an autowrecker as they are pretty pricey from the dealership.
