[P.J.]

another way to do it is
Take the sprigs to a local leaf spring shop. Mine was called ( Hard Dick Springs),Honest! where they will compress the springs to the max., then Strap them in place with steel straps in three places. Then place them in the location, hook up the arm back in position then take wire
cutters and cut the steel staps one at a time and bingo they are in. Take the steel straps out in pieces.When you cut them off the spring snaps into place.
no fuss no muss.
