What conversion do I have?

[99turbogmc]

I bought a 1970 c10 swb with 6 lug all the way around, disk in the front. I have 6 broke wheel studs. Have no clue what to ask for at the parts store but no biggy.. How can I tell what I have? Basically I'm trying to buy drop spindles and don't know what to buy or where to start..

Also, even though it's 6 lug, is it going to be standard GM 6 lug bolt pattern? Reason I ask is because the wheel studs are thinner compared to my 6 lug 99 GMC Sierra 1500.

Post some pics of your spindles rotors and a-arms.
That will help for starters.
The pattern will be the standard 6x5.5 and the lug studs should be 7/16" thread.
