Wheel bolt pattern 91 metro convertable?

Why am I having an impossible time finding a cool set of wheels for my 91 convertable?
What is the pattern called?
Is it different from regular Metros?
I measured the lugs at 3.25 inches center to center but thats only 82mm. I see 4 x 100 and 4 x 114s everywhere.
Am I missing something?
Also need top parts, weatherstripping mostly..... Tnx.

All metros have a 4X144.3 bolt pattern. The convertibles have larger studs on the hubs, so it'll make it easier to fit rims.
