The bolt pattern should be fine, the only concern is do you have a full floating rear axle or semi floating. If its the full floater, check center on the hub and see how far it sticks out. If its more than the 2 inches, you will have a problem getting therear wheels on because I dont think the centers of the wheels are big enough to go over the hub. The spacers in the front should be sufficient to clear the hub. Id check for an option of 1-1/2 inch spacers in front and 2-1/2 inch in the rear to pull the rears out a little to help line them up with the body a little better. I have those 18s on my work truck and kinda like them. They look good on squarebodies
