Re-assembling the square - best order to do things?

[Mattchu60]

Well I spent the last 3 days completely taking my truck apart, she is in pieces laying in a shed right now. I am swapping the body over to another frame which I blasted and painted over the winter.

I am finding there are many differences from my new frame (83') and the frame from my current pickup (87'). For one - they must have started using metric bolts for everything that bolts on the frame. There are many other little updates, like the middle crossmember has additional supports which i need to swap over for the fuel tank switch to mount on.

After i get everything moved like fuel lines, I'm putting it back together. My original plan was to install the engine/trans first, then put the cab on and then the front clip last.

Then I started thinking maybe I should install the trans first, then the cab and the engine after. Or do the cab first, and try to slide the whole engine/trans/transfer case assembly under it.

Any thoughts - just looking for easiest/fastest way to do this.
