I purchased this truck about 2 months ago , been trying to get everything on frame as dirt free as possible, today I got to front end of truck, pulled skid plates and get to looking . I have a stamped bolt in lower ball joint on right side and left side is stamped lower arm with forged on outer ball joint area. Upper control arms are 12 1/2 inch outside width right next to bushing/pivot. Hubs are 8 bolt. My questions are , Is this a 2500 frame ? Which lower control arm do I need to replace because it will need front end rebuild
