[Vic's 1987]

I just put rims on my 1987 Suburban, but the spindal and nut comes out too far past the wheel so i am not able to place the center cap on. It is a must that I be able to tuck the wheel due to future bags. Is there a way to fix this without using adapters. I'm don't know much about the this stuff as i'm sure you can tell. please help! Thanks!
