Drop Spindle Question

[robs_c10]

This might sound like a stupid question but I am in the process of restoring my 69 C10. It was lowered "the wrong way". The frame was all chopped up in the back and front well.....I fixed the rear suspension with real drop springs and blocks with a real c-notch kit but now i need to work on the front. It looks like it has cut springs, with a bunch of washers spacing out the A-arms. Is there a way I can tell if the spindles are dropped or stock? I want to lower the front at least 4" if not 5" but I want to ensure it handles well. Any recommendations on "front only kits" or what I need to make this happen? Any assistance in this would be appreciated.
