U bolts

[dammitmitchell]

hey gents!
well i lost a u bolt (well it wore out i guess...)
i need 4 new ones for my 14bSF rear

the question of the day is..
with a skyjacker 8 in lift...

what bolts do i get?

and where do yall reccomend getting them.. the local guys stare at me funny and my trusted napa guy said "you'll save alot of money ordering directly"
the local truck shop dosent have the correct dye to make the bolts i nee. ("we dont have any small nuff for that one youngin")


input?
what measure ments do i need to take?
width of axle? or center of hole to hole on the plate that sits on my leafs?
height?
how far past the plate and nut should i go to ensure my on safety?


thanks for the input guys.. i dunno why but im pulling a maaaaajor brainfart
