Need help with rims?

OK I have 17 inch rims on my van atm. Originally the rims were on a 1995 Nessan Quest but I just purchased a 1999 Chevy Astro and got a conversion kit so the rims would fit on it. My question is I have Spinners that I would like to attach to these rims. They were on the rims when it was on the Quest but now that there is a spacer on the rims I am told that I need a special lug nut bolt for it. Does anyone out there know exactly what I would need to get these hooked up. According to the guy who did it the part I need is sold out so I would like to check around myself and see if I can find it. And yeah I know spinners on a van is stupid but it's to advertise my business.
