But what I’m having a problem with when I’m going searching for is the offset for my front end/wheels...how do I find the offset on the factory wheels that I don’t have? Can you help me with that?

I've never dealt with the backspace myself as I am running factory steel 5.5 wide. I really don't think it comes into play much on the front. A standard wheel should center the tire in the space and work fine unless you go too wide as it is now. You are probably close on the inside of the tire as well. Here are a couple calculators that will either help or confuse the hell out of you. :eek:
