Different wheel offset with newer spindles?

[68jimmy]

In the FAQ section one member posted that he used 90 3/4 ton spindles and brake hardware when upgrading his suspension. I was thinking of going the same route, but got thinking, when using the newer spindles does that change the wheel offset? I was wanting to use a set of original 6 lug rallys on my truck, but before diving in I thought I'd ask...

Thanks!
