Need 15" wheels with 5x4 bolt pattern

Hey guys,

I'm looking for new sweet looking wheels for my 1965 Plymouth Valiant convertible. I want to go with 15" wheels but having trouble finding the 5x4 bolt pattern. Anybody know if 100mm will work? If not, any suggestions what wheels and where you can buy them. I don't want to convert my front and rear to a larger bolt pattern. I would appreciate your help.

Thanks,
Alan
