Outer Limits 4x4 Board

Hi all want to know how to change the transfer case on r151f gearbox and us the g52 transfer case
Have found a r151f gearbox and it has the vacuum operation on the transfer for auto locking hubs and mine is manual locking hubs is there a way I can use the vacuum operation on the transfer case or just swap the transfer case
I'm running g52 gearbox behind v8 atm and have found a r151f at a good price is $650 a good price

If I can swap the transfer case do I need to get something else to do it
Don't want to buy it if I can't do it
