Default 1998 wheel offsets

I'm getting ready to buy some new wheels for my '98 and am having trouble finding the factory OEM offset measurements. I've gone onto at least 5 different wheel vendor web sites and each has different offsets for the front and rear wheels. I don't know how critical the offset number is, but I'd like to replace my wheels with the correct OEM size.

I've seen 56mm, 58mm, 54mm, and on and on for the fronts, and 58, 61, 64, and on and on for the rears. Where can I find a definitive chart indicating correct factory offset numbers for my car? And if the offsets are off by say, 2-4 mm, is this possible? I'd really just like to have the correct factory numbers... The last ones I found were from Mid America works and they were 17x8.5 front - 56mm offset - 18x9.5 rear - 61mm. TIA
