while you are removing rivets, why don't you remove the rear hanger and do a shackle flip?

then flip your front one to drop it a tad more.

the one thing I don't like about my drop shackle is the wheel hop I get with the stock/drop shackles and axle under leaf.

with the shackle flipped and axle on the top of leaf I get no wheel hop what so ever under the 440 truck or the stepside.

the drop shackles and 5 speed are giving me fits with the axle under the spring/stock or dropped. the locker will bounce the tires super hard.

I have a set of SSM lift bars that were on the 440 truck and worked great with the mono leafs I had under there but I went back to stock leafs.

I will be flipping the stepside axle back on top of the leafs with the SSM lift bars to control the wheel hop with the 5 speed..I hope
