2002 Mustang Bullitt Wheels on a 1969 Valiant

I have an all-original 1969 Plymouth Valiant Signet 4-door and have been looking at some wheels and tires for it. Trolling around the web, I've seen some posts of people putting Mustang Bullitt wheels on Dusters and Darts. I'm assuming that I can put them on my Valiant, correct? They are 17 x 8 rims with 5.72 inches of backspace from a 2002 Bullitt. I have 245/45/17 tires for them already. With exception to spacers, will this wheel and tire combo work correctly on my car without any modification to the car itself? I appreciate any replies. Thanks a lot.
