I also felt your pain a few weeks back trying to fit a 4x4 engine/box etc complete after dragging it singlehandedly across the front garden from the old car as it was seized in solid.

Then discovering most of the car underneath was different as it had been converted to 2wd hence needing to swap just about everything over as well!!!

Still I bought one of those electric impact drivers from Clarke halfway through the build which was awesome,just annoyed I didn't get it before I started!!!!
