I finally got it in last night, what a nightmare it has been!
I would prefer to do engine swaps and rebuild any day of the week than do another one of these on my own.
One slight hiccup is I didn't remove the diff locking pin ( a u shape piece ) and the lever before pulling it out, fortunately I can pick up replacement bits next week.
Tonight I'm bolting the props back in ( handbrake mount & cable swapped ) and rewiring it all to the box and cross fingers she'll be ready tomorrow
