1978 W200 Tranny swap/transfer case overhaul
 

Just wondering if anyone has done a 4 speed to a 5 speed tranny swap on a 1978 W200 truck? pros/cons and any help/info would be welcome. It is my first project vehicle and the kids and I are excited but overwhelmed.


Also I would like to go through the transfer case and but new bearings in and oil of course. is there anything else I should do to it?

What are you going with? NV3500/4500, or...???
