Sway Bar Opinions?

My dart has the .890,and I modified the K-member to accept the 73 style swaybar(it passes though the K)I`m using a 1 1/8 swaybar from PST.And have Polygrapite bushings.I have KYB shocks all the way around.It handles great!I`d like to install a rear bar,but don`t know if I can find one for a car that is mini tubbed.
