I have four USA made old school 16 and 1/2" diameter by 9 3/4 " wide aluminum wheels with an 8 lug on 6.5 inch diameter bolt circle. I removed the junk tires. I don't have any center caps. These are for use obviously only with 16.5 " diameter tires. Might be good for mounting surplus Humvee tires on . If you're interested give me a call at the number in the above reply box. Would trade towards Chevy square body stuff or Ford OBS stuff or other mechanical junk. 92-97 rust free F350 steel wheels or the old classic 1970s wide Chevy square body steel 16.5 rims .and hubcaps
