What Wheel Backspacing for an F-Body 8.25 in an A-Body?

You have to go back past ‘97 for the Crown Vic cop wheels to be 15”, those were 15x7 with a 4.25” backspace. After that they went to 17”.
Looking at 17s now. There are some reasonably priced new steelies that have over 4.5 offset on a 7" wide rim, so they might have a chance. Just looking at options at this point, going to put it all in the car and measure up everything before I get wheels.
