Gx 470 Rims On Lx 450

[jimbee8]

I have owned a 1997 Lx450 for approximately 5 years now. I love my truck. When i bought it, it had a 3-4 lift on it already. I just purchased some used GX 470 rims cause i know they woould fit. The only issue i have is that the center caps do not fit becasue the hubs on my LX450 stick out too much. Does anyone have any ideas as to modify it so that it will fit? Would the use of spacers help? I really like the look ofthe rims but don't likethe hubs exposed.
