I have an 81 F250 that I am parting out that has 16's on it but I'm not sure how wide they are. They are the original stock wheels. I also have a 75 F350 chassis that has wide wheels on it (single real wheel F350 not dually). I think they are rusty chrome wagon spoke type wheels. I'll have to check next time I'm over at Mom's. If you are interested maybe we can make a trade.
