RE: Are these rims going to fit??
Well, backspace is the distance from the inner mating surface to the inside edge of the rim. On a 9 inch wide wheel, a backspace of 6.4" means that most of the wheel ( 6.4 inches of it) will be "tucked under" the car. On our stock rims, 3.5 inches + 39mm(approx 1.5 inches) = 5 inches is "tucked under" the car.
So, your new wheels will be "tucked under" the car by almost another 1 1/2 inches compared to stock.
I don't think there's enough clearance in the front suspension for that kind of backspacing - you're probably going to hit something.
If you keep your *total* backspacing to about 5 - 5 1/4 inches, I think you'll be OK.

Are you sure the backspace is 6.4"? With an offset of 36mm, 6.4" backspace equals a 10" wide rim!! A 9" rim with 36mm backspace would be about 5.4" backspace. You'd be real close to the spindle with an 18x9 rim and 36mm offset, but the larger 18" diameter would probably be enough to just clear the spindles. And there's NO way you'd want to use a 1" spacer. You'd need to replace all the studs, plus the centerline of the wheel would be way outside the centerline of the bearings, really stressing the bearings with additional side-force.

You guys seem to know something about rims and the various sizes. A lot of us Car enthusiasts are looking to replace our stock rims or replace rims for another set.
Maybe you guys could draft up a word document/article about this for the newsletter. Sure would be a helpful and handy piece to have.
I know Sleeper needs some articles.
Thanks.
