Question about converting to 80's suspension

[AustinBelair]

My brother and I went and found an '83 1/2 ton truck and gutted all of the front suspension. I've already bought new tie rods, ball joints etc but now I want to lower the front of my dads truck while we rebuild it.

Should I just buy some 73-87 drop spindles or buy the 3" lowering springs? I was tempted to buy tubular upper control arms as well.

I'm about to have all of these suspension pieces sandblasted and painted so I thought I should before I blast and paint the spindles.

Thanks guys
