Which front sway bar?

X10 on the Hellwig. I put their front bar on my 69 B'cuda...had a question on the hardware provided. Called them and an actual person answered, connected me to another actual person who answered all my questions and sent me what I needed at no cost....no questions asked. Decided to put their rear bar on....this time I had questions on the install. Called...they transferred me to an actual person who had obviously actually performed the install on these vehicles...he knew EXACTLY what I was asking and EXACTLY how to remedy the situation. Excellent product with fantastic customer service!!
