Rear springs used for sas?
 

I've got an 88 short bed pickup that i'm building a driver/wheeler out of. I want to use the 63 inch chevy spring on the rear but i'm not sure what to do on the front yet. I'm looking for 3-4" of lift(I'll be running 33" rubber). A buddy of mine tells me to use rear springs off of a yota. Has anybody done this? Will they flex as well as lift springs? How many leaves do you need to use? How much of a drop hanger and how long of a shackle?

Pretty much about a billion people have done this.
