hate to ask 73 dart sport 15-16s?

I put factory 15 x 6 1/2" wheels from a 77 Chrysler New Yorker with 205 70 15's on it on my 75 Sport. Made a big difference improving the handling and stability. 205 70 15's are about the biggest tire I'd put on the front of that car as they are real close to the edges of the wheel openings at the very bottom of each. Sport came with factory 10.87" disc brakes.
