i know--i know---an 89 d250 is an 8 hole-----and those cool 17,s you see probably wont fit your truck because of an increase in the offset---so if you had a first gen cummins truck and you wanted those cool aluminum 16,s on a second gen truck you would find the front rim hits the tire rod end and the back rim wont fit over the rear drum----now on the even cooler 17,s you find the rear will fit and the front still is hitting the tierod---of coarse you can spend 100-200 on some cool wheel spacers....
