I would do some good research on those fenders to make sure that they are the same. I have a fealing that they are NOT, But I am guessing. It wouldn't suprise me though. dodge and plymouth had interchangable parts with different years. example 1969 barracuda hood is the same as a 1973 and up dart hood. go figure.
can you Pm me if and when you find out if the fenders are the same. that would be good to know.
make a new post for the fenders question...someone here should know. then again, sometimes you have to figure things out for yourself ;)
