Nice score for $400. I had a 76 GMC High Sierra C15 handed to me. It's an auto body nightmare, not sure if it's worth restoring. Too many miles I am sure. It's easy, cheap to fix and service lol. When I swapped a steering knuckle the ball joint just fell out of the lower control arm, put a new one in to hold it for now but I need to find out how they are held in. There is no taper, rivets, bolts, snap right or nothing so maybe it is just the weight of the vehicle that pull the lip against the control arm? I need to get an alignment done now so maybe the people at the shop will know how they are attached.
