Yep, bolt in just fine... Only difference is they are about a mile wider. Edit: When swapping to a 9" rear, some folks have needed a conversion type rear joint. They make u-joints with one bearing size for the shaft, and another size for the pinion.
A mile could be bad, but 2-3 inches on each side would be just fine, since I currently run spacers with the late model wheels.
I have put my 05 Mustang wheels on my 70 Maverick and put the GT wheels on my v-6 Mustang, of course you will need spacers. I have a picture of what they look like on the car.
05 wheels My project maverick, 05 wheels with spaces... Just waiting on the new mounting brackets to install the 12.5 disc.
