On a Coronet R/T? Some cars are more tolerant of the large backspace than others. A couple years back, someone on Moparts posted photos of their Coronet R/T (69 model) with 17x9 or 17x10 wheels on the rear for sure, and maybe on the front as well. I've slept since I saw it, but I remember being amazed at how well the wheels fit with no mods. The hub bores on the Mustang wheels are going to be too small to fit the Mopar hub, so you'll probably have to use spacers like Jerry's with the proper hub sizes, or have the wheels machined to fit the Mopar hub. Ideally, you should have the wheels opened up to 73mm so you can use common wheel hub rings to fit the Mopar hub. Then you have wheels that aren't Mopar-specific if you want to sell them in the future.
