Which Torsion Bar?

I'm running a healthy all iron 360/727 and a 8 3/4 rear in a 70 Dart.
I have 1" T bars from Just Suspension with a Hellwig 1 1/8" swaybar on the front.
I am using a 3/4" Addco swaybar on the rear with KYB shocks all round.
Frame is tied with US Car tool weld in ties.
I'll buy better shocks and move the battery to the trunk someday maybe.
Don't know that this helps you but I feel its a pretty good balanced budget build
for street and limited autocross use.
Every things a compromise unless you dedicate to a special purpose, its easy
to over do it and end up with a log wagon.
