I went with the AlterKtion.
You have many options as far as motor mounts , or not , sway bar , power rack etc. etc.
I run a motor plate and opted for no sway bar since it is more or less a drag car.
The closest I come to a complaint is that the track width is a C.H. wider , and with 15 " rims , it just scrubs the front of the pass. side wheel opening at full lock turns.
This is on a Dart.....I do not think this issue is on the B body kits.
It drives like a dream.
