The Back section needs to come forward about 1/2" which with carefull
trimming should close the gap up. On the original section you can still see a
smear of lead, that lead was at least 3/8" thick in places, it will fit a lot closer
then that by the time I have finished.
Unlike the USA Skirt panel which is bolted on the Australian one was
spot welded in place a real pain to remove.
