"I'm still going to use the lower control arms and swaybar though for my '74" Duster.
The Duster has spool mount k-frame but didn't come from the factory with a swaybar.
The Dart will use either a spool mount k-member or the early style with a large aftermarket swaybar.
I was going to use the '67 k-member that was in the car (after all I already own it) but the thought of the one year only idler arm keeps nagging at me...
