Spanky,
Do you know offhand if the front spring hangers can be swapped between the 400 and 300? I understand they are different, just curious if they use the same rivet holes/pattern. The rear of the front spring hangers do look swappable.
I ask because the frame on this truck is complete junk and we could find a 2 ton frame pretty easy, then swap axle, springs, hangers, and fenders + inner fenders.
