The 1572/1772 driveshaft length is different than the 1872/2072. For a 1572/1772, use a driveline from an 1863/1864, a pump adapter from a Cyclops SGT, and either make the engine adapter 1/4" thicker than original, or use the engine adapter from a 1782/2182 with 1/4" spacer. Chances are you will have to make it, because there are not many 1782/2182 tractors at the wreckers. You will have to tap the input shaft of the pump 1/4".
