I’ll keep it short. I have one piece transfer , is there a two piece transfer that will interchange ?
Not without changing the transmission or very custom one off output/input shaft adapters.
 
I am sure the adapter that was first used between the 4 speeds and first split transfer case would replace the original you have.

Going by the user name the cruiser in question would have had a J30 three speed. The part numbers are different for four speed housings. 4/76 the case had a change because of the extra bolt added. Since the the back plate is bearing retainer and bolts pass thru. Pattern may have changed. Then your would still dealing a transfer case looking for a nineteen spline tailshaft out of the transmission. For a four speed just using a FJ45/HJ47 from 8/80 plus would be an easy solution. Would still have the transfer case hand brake.
