Would these wheels fit?

no those appear to be a positive offset. at 45mm. you are looking for something with a closer to a +/- 0 mm offset. your best be would be to go to tirerack.com and search by year/ make of vehicle. helpful hint**** if it fits a newer front wheel drive car it will not fit your stang... there are a ton more things to consider but you need to find a wheel with the correct offset, then you can choose rim diameter/width/backspacing and tire size....
