Identifying original body panels

[skyman51]

I am new to Mopars particularly older ones. I recently bought a 1963 Dodge Polara. It is supposed to have all original body panels. I have always had Chevys and the original quarter panels showed the factory spot welds in the gutter where the panel met the trunk. It also had a batch number stamped into the gutter near the top of the quarter. Do Mopars have any similar indicators of originality?

I guess I'd look for real "pinch dimple" style spot welds vs drill and plug weld. Also look for evidence of mid panel splices.
