1958 dodge d100 rear brakes

Is it taper axle ? If so, I believe the up to 1964 10''x 2 1/2'' rear brake set up will work.
I ask because I too apart a D100 1958 rear that only had 1 wheel cylinder per side.
Same as the passenger car.
It was taper axle. The pumpkin was a 658 casting # with 3.58 gear ratio.
Sorry I don't have any parts left over any more.
