Did Darts only come with the small wheel bolt pattern?

stock small bolt axles? if they are aftermarket large bolt axles one could be for the standard A body small bolt drums the other could be for the b body style brakes.

I think that I figured out that this rear has the longer A body axles for B body brakes and thats what is pushing my width out.
