make sure you flip the center pin on the leaf springs.
as for the hangers, good luck. if they are anything like nbs trucks then its a pain to get the stock rivets out.

 

I am an aircraft mechanic so luckily i got some special tools and tricks but i just haven understood the concept my kit did not come with new u bolts do i just use the old ones?

 

yes just use your stock ones.

and either drop and move your gas tank to drop the driver side leaf spring so you can relocate it under your axle
OR unbolt your driveshaft so you can swing the axle over your leaf springs.

 

ok thanks guys!
