Finally its going back together.
I've got to remake the engine floor and hopefully repair the gearbox floor, both 1.5mm steel. I imagine originally 1/16th.
Gearbox floor
Right side is from the 44 Ford range target, left is from an 42 MB Wild.
Engine floor
Left is 44 Ford, right is 42 MB Wild...there is nothing in the middle, I presume to let the oil leaks drain out
