'79 GMC frontend drop help

[ymerej71]

Hey everyone, I could use a little help / info dropping the front end of my '79 GMC. The truck had been dropped some before I purchased it, but the guy I bought it from had no info on what methods had been used... I'm guessing maybe different springs. I'm thinking that the spindles on the truck are the originals. I'm not wanting to go much lower for now, just wanting the tops of the tires slightly tucked. I've attached pics of the frontend, springs/spindles and a pic of the way the truck sits now. If you can tell... do you think that these are the stock spindles? If so, new dropped spindles are probably going to be the route I'm going for the extra drop. Let me know your thoughts... Thanks!
