I was just looking through my kid's literature on his 1999 sebring and noticed that HIS bolt pattern was 5 x 100mm or in my world 5 on 4" but didn't see the back spacing on his. will they fit the early a bodies?63-66 dart and valiants. and can you find them with the correct backspacing needed to look good in the wheel well. I saw 15" through 18" listed as a fitment for his car and was just wondering if anyone has tried them?
