Not without good reason

Not with out good reason.......is aligning, or rather inserting the top bolt in, the diff known as the hardest job. I nearly swaged three spacers in to the top LH bush, but after some precision engineering it is aligned to a the tightest tolerance the measurement uncertainty on my measuring instruments would allow. +-0.5 mm

For good measure I also removed the BMW shafts and stuck in the caterham ones

The only other thing I managed today was to replace the gearbox support bolts with the correct ones that Derek had sent them over.
