73 Dart front Hub to Hub measurements ??

I have decided to install a Speedway straight axle kit to my 73 Dart.
The Darts front end was/is completely disassembled when I bought it and I don't have an easy way to determine the front hub to hub measurements.
Does anyone have these measurements? I need to know before I order the kit what the stock measurements are.
Thx in advance, I appreciate the help,
Bill
