Is the rear 2wd driveshaft flange the same as the front flange on a 1982 D50 4x4

I have a 1982 2wd D50 and the rear driveshaft flange that bolts to the rear end is destroyed. I found one out of state. Its out of a 1982 D50 4x4 front driveshaft. Wasn't sure if it would work on the rear. Thanks in advance
