Super duty front leaf springs

I'm about to do a pmf rsk. I just have one question, I order super duty v code springs from ats, I ordered there whole kit that comes with all the hardware needed, but I didnt think to question if superduties and obs truck use the same u bolts? If anyone has any knowledge on this please chime in.

Re: Super duty front leaf springs

Great question, I’m trying to remember and think I just used my OBS U bolts for the PMF RSK. What I did notice on my Tan White Tan truck conversion, it passenger side under axle base plate may start to distort when torquing to spec of 150lbs ft. Seems I got to about 90-100, spoke with my off road builder who has done tons of this work and said that was not unusual and should be fine. Thinking an extra plate on the bottom side of the base plate would prevent the stock (welded on one) from distorting. It’s a ways down the list as of now.
