Hi
It will be an easy swap.Everything will pretty much bolt in.
Some different pieces between the two trucks you will have to change
Fuel caps
Tourque converter,trans governer
Radiator
You can simplify the wiring by building your own glowplug system,or change the engine bay wiring harness,possibly the under dash if you want the stock glowplug system.
If you have some basic mechanical skills this is a doable swap for a weekend.Not to much to convert.
Some things you may want new, like motor mounts the old ones are probley wore out .
Lots of room to work in.
You may want to freashen up the donar motor while it's out if you don't need the truck right away,head gaskets, oil seals, timing chain,injectors tested and balanced,glow plugs,waterpump,ect.
Any how that touches a few things,i'm sure you will get a few items i missed by some of the others on the site.
Great Truck,i have two,am looking for a couple more for parts,i want to drive it till i die,NO STINKING COMPUTER
Get a preasure washer so you can give everything a good bath befor you start and after you get the motor out.
Have Fun
