The only 6 lug 14 bolt comes on the next generation truck from yours. The 88-98 2500 light duty, if your suburban is in fact a v1500 it's the older body (73- 87) just because the suburban didn't change with the trucks until 92. If you found one it will NOT BE a direct fit. You need to get a 10 bolt from the same body style truck as yours to be a direct swap
