Removing Lowering blocks

I just bought this 97 tacoma Xtra cab and it was lowered when removing the lowering blocks what do I either put in thier place or how should I put it back together?
In shorter term how can I either unlower the truck completely or raise it as close to stock as posible?

 

all you need is to take the blocks out, and get shorter u-bolts to tie the axle back into the springs.

also, while you're doing that, it appears that the passenger side brake cylinder and/or axle seal is leaking as well, and should be addressed soon.

 

Ok thanks for the advice and noticing the leak didn't even notice that
