Question about enkei 92 centercaps.

So before I left on vacation I bought some centercaps (would post link, but the fs add appears to be gone now) from member nathannelsonross. The people taking care of my house told me the package showed (very promptly I might add) so i didnt worry to much about it. Well once I get home I open up the package to check them out. They look as good as a oldschool centercap can look so I run out to the garage to install and the things are too small by about a 1/4". ive pmed him about it, but have yet to get a reply.
Anyway, my question is, do the different sized wheels use different diamter center caps? Im wondering if these caps are for say like a 13" wheel where as my wheels are 16". Ive poked around the net a little, but searchs dont yield much info about the actual centercaps. I ask this here cause I see so many of the wagons with this style wheel. If anyone has anyplace they know for good info, Id appreciate a link.
I guess if I could ask a favor to those with these wheels when they have a minute to put a tape measure on thier centercaps (or at the least the hole they fit in) and maybe post up your wheel size and the width of your centercap center to center.
TIA for any info provided

wheels are definatly enkei and the way the logo looks is identicle. both (caps and wheels) are oldschool with slightly bolder style font. whatever the caps belong too, they are definatly near the same vintage. dunno Im lost.
