Shopping for Wheels - 69 2000

["Meston, Larry/EXEUG3" <lkmeston@pscnet.com>]

I'm looking for custom wheels for my roadster.  I know the current wheel
size (i.e., 14", 4 bolt, 4.5" centers), but when I ask local wheel vendors
what will fit my car, I'm met with blank faces.  Are there more precise
metrics that I could use for specifications, or is there a "modern"
make/model of car that I could use for a reference instead of the roadster??
Thanks for your consideration.
