mock up engine and put the body back on.
Be careful here. I have had to move the firewall (via a hammer) to get the turbo to fit (isnt finalized) and there is another space issue by the accelerator lever on the back right corner of the engine near where the heater lines to the cab are. You might find that the body doesnt fit with the engine and some modifications are needed. I am also possibly (needing to confirm) running into an issue near the clutch slave cylinder.
