man i went with the he8s off of airbagit.com buy 2 get 2 free i think it was 220 or somewhere around there for all 4 all i lack now are all the fittings probly going with compression fittings from local hardware store they are pretty fair priced compared to most i've found online.
managed to get most of the unwanted brackets torched off the rear of frame and cut out front coils before the torch ran out of oxygen
most everything was welded plus the factory rivets the tow package and gooseneck plate are next to go once i get it refilled
this is about what ride height i will be shooting for
