I am having a hard time finding replacement lower control arms for my 1st Gen. 3.4 ton. Does anyone have any used ones for sale? Or do they have after market ones? I haven't had any luck finding any. Also does anyone know how or if I can tell if I have 3300lb axle or a 4000lb axle?

My truck got hit and my right lower control arm is severely damaged. The left one is not in great shape as well

Any and all help greatly appreciated.

Thanks
