If that is factory 68 superstock Dart those were the original fenderwell
produced on that car. Most of those SS/B cars ran 14 x 32 Slicks as I recall
but some ran a 12.2W x 31.25 if my memory serves. I have owned 3 of them and one was brand new.
I believe someone on this site has mentioned a template for those that
is available but they varied a lot car to car. They were pretty crude.
