i put a nova rear end on leafs on my bucket. i used the lower bottm brackets form the nova rearend an i went to a local trailer shop and got u bolts and also weld on spring perches from them that fit the rearend dia . i mounted everything loose on the springs and lined everthing up so it was straight and got the pinon angle right and then tack welded it all and took it apart and welded it up. i mounted the shocks inside the frame and flipped the lower mounts backwards for more tire clearance. it worked really good. the toughest parts was grinding the ugly original nova spring mounts off the rearend.
