Shock and spindle question
 

I'm going to redo the suspension on my 68 swb and had a couple questions.
My front end makes loud clanking noises when I hit bumps.

I have 2 1/2" drop spindles up front and 4" drop springs in the rear. From what I've read I don't need shorter shocks. Is this correct or will I need shorter shocks? What brand shocks do ya'll recommend from oreiley's?

Also, I have 6 lug disc brakes up front. How do I know if I still have 68 upper and lower control arms and 68 spindle or if they have been upgraded to a newer year? I need to get ball joints and don't want to make a dozen runs to the parts house looking for the right part.

Thanks in advance.

Oh here are a couple crappy pictures if it helps.
