remove the lift block between the leaf spring and the axle or put a smaller one in

Go get a lift shackle from a parts store. The rear end has flipped shackles so by putting a longer shackle on you'll actually lower the rear.

Aftermarket U-bolts for lift blocks are mostly the same size. Although, the general rule is you don't reuse U-bolts. The shackle is what the leaf pivots on. If the spring was attached to the frame at both ends with out a shackle on one end, there wouldn't be any cycling of the suspension in the rear because as you flatten out a part of the circle, the location of the points of attachment would have to move. The shackle accomplishes this by letting one end move back as the leaf flattens out. Lift blocks are cheaper, but it becomes easier to torque the axle with them, ie you could see wheel hop in some instances, cause premature failure of the U-joints, or even break a driveshaft. These are highly uncommon unless you are running high horsepower or high torque applications.

I'd just put a smaller lift block in given that there is already one there. Or see if you can't crank the torsion bars up front if your running 4WD

It's a 2wd and can I not take the piece of the back that holds the shackle, and drop the shackle down and put it the bolts back in where the thing that held it was?

Buy a two or three inch lowering shackle. Just unbolt ur old one. Knock it out. Bolt in the new one. They cost like $60 Easy 30 min to an hour project.
