Being that your running leaf springs and you
need a back brace.. you can run a wider one all
the way to the outer side of the spring pads then
turn it in.. that way you run the spring bolts
thru the back brace.. if you stop it at the spring
pads the outer ends will bend.. this is my 9" but
its for a ladder bar.. but you will get the idea
at where the pads would be.. on mine you can see
its angled all the way... yours wont be angled in
as much till after the pad.. I've only done one this
way.. most dont use leafs
EDIT
you will have to move the shocks which you should
do anyways to mount then vertical
