Hi Eric Szalanda
Im sorry to say that you will probably not find what you a looking for as English universal carriers aren’t as plentiful as Australian produced ones but hope is not lost English and Canadian Carriers are identical and you could order what you need hear is a link to Midwest Military
http://www.midwestmil.com/brencarrier.html or you could have the parts made from work shop drawings but make sore that the drawing are for an English carrier as Australian Carriers are slightly different in size and construction. I think there is drawings in the numerous manuals for the carrier your best bet would be the work shop manual you could post an add on this sight for a manual and you should be able to find one.
