burned truck

[xshadow]

I'm looking a a 4x4 truck that caught on fire.
I want to buy it and put my 2wd body on the frame. both trucks are 67-72s
Do you guys think the fire would have messed up the drivetrain. auto trans or transfer case?
The fire was hot enough to burn everyting in the cab, and I mean everything. If it wasn't metal it isn't there anymore. It warped the dash and headliner area.

It also melted everything under the hood that wasn't metal. It even started to melt the carb. Some of the plastic is still on the battery and cables but I would say less than 1/2 is still there. The crome valve covers still look crome and the block still has orange paint on it.
The plastic hubs to lock it into 4wd wasn't harmed at all. The fire burned one rear tire but not the rim, and didn't burn any paint on the lower 1/4 of the truck.
the cab floor is rusted...well there is no cab floor on 1/2 the truck just a BIG hole, It has sit for a while with no paint or windows.
I have a good 2wd body & engine, on the most part everything on the 2wd 3/4 ton is good. I just really would prefer a 4x4.
I figure swap the body and engine. Steering post, Put new rubber break lines that are near the wheels? What do you guys think? DO you suspect the drive train and frame survived the fire.
I really really don't think the engine would have.
