Took my nephew to the beach today, and the surfboard. Got mildly sunburnt.

More succesfully, the evening was spent in the garage. After removing the two sections of boot floor I could get enough of a bend in the dividing beam to get the lower diff bolts in. Only needed one washer on the RHS to get it central.

Then to the top bolt: had an initial measure up and decided that two washers for the LHS and one on the right would be approximately central: put those in place and gently tightened the bolt, re-measured and was surprised to find it was dead centre, result!

So torqued those bolts, attached the prop shaft to the diff and torqued those bolts too, then called it a night. Will need to find out from Derek if its okay for the diff to be touching the boot floor, or whether I need to drill out the rivets and space the dividing bar away from the chassis with some washers.
