Drop spindles that ADD track width?

[Janz99]

Hey guys, I in the market for a set of 2-2.5" drop spindles for my 68 C10 with drum brakes all around. The set of wheels I am interested in as well only comes in a +12mm offset. If I could get a set of drop spindles that pushed the front wheels out 3/4 to 1" I should be able to make them work.

I've heard the CPP modular spindles don't add any track width, but what is that in relation to? A stock disc brake or drum spindle truck?

If anyone has info on some of the different spindles and how much they push, or suck in the wheels it would be greatly appreciated.
