Is it that you've just worked out how many kilos of filler and welding wire have gone into a "very light" truck since you pushed it through the door
Am keeping my fingers crossed you squeeze it all in...otherwise the next sequence of photos will be "take the front end of an Aprilia, cut here, weld to the rear 2/3rds of an Ardea pickup that was cut down from a van that's now been split lengthwise and widened to match the Aprilia bulkhead".
The only other combo I can think of is a Gamma engine under the rear deck
