oooh, I think I've left that one at work. I'll reply monday unless somone else can find it first.
I think they did it from the bottom up tho - Wheels, axles, (new springs), Transmission, engine, Then undid all chassis to body bolts (correction, ground off most)Electrics, then lifted the entire body straight up and supported on trestles and scaffolding. Dragged old chassis out, and rolled rew rolling chassis in. Spend the next two weeks fitting it all together and that should be about it ??
Find a good engineering merchants for all your new bolts, as it would be well worth while buying a bag of 100 of each- stick with the imperial.
Good luck.
