Pops 1970 C20 Suburban

[Mr Pops]

I just bought this C20 Suburban in the hopes of using it as a daily driver. It was redone in 2003 and then parked for 10 years. It's got the factory 396 (402) and a Turbo 400 tranny.

I want to convert it to a 1/2ton and I'm leaning towards going with 6 lug instead of 5. The donor rear axle I have is 6 lug and I wouldn't mind running 6 lug GM rally wheels on it.

So since I want disc brakes in the front, but with 6 lug rotors, can I piece that together with stock parts instead of ordering the kit? I know some 1992 Chevy 2500 2wd trucks came with 6 lug instead of 8, just wondering if I could use those rotors on a spindle that would work with my control arms, or do need to change control arms too, or am I better off just buying a kit? I'm thinking of doing about a 3" drop on the front, but don't want 3" drop spindles if my 15" rims will hit them. Maybe a 2" spindle and cut a loop off the coil..
