Reproduction wheels/caps

Good afternoon,

I'd like to replace my 15" American Racing Torq rims with reproduction factory steel wheels and dog dish hub caps.

My questions are, what is the easiest size to put on? 14's? My Dart is a 67. Is the wheel pattern 4 1/2?

What were the stock rim sizes for the GTS?

Anyone know of a source for repro steel wheels?

Thanks,

Doug
