Any of you guys running 2.5" F150 Leaf Springs with flipped shackles?

[Shawn@BMS]

Hey guys.
Just wondering if anyone of you guys are running 97+ish F150 (2.5" wide) leaf springs? Seems that there semi popular with flipped shackles. I think there 57" long so you dont have to relocate the front leaf spring mount. Just looking to see if anyone has any first hand experience. Im not bothering even posting this at DR. To may flamers over there. Search is worthless there as well. Any details would be nice.

Thanks,
~Shawn
