Karcraft lists a short boot kit GSV1153 for Oz racks, and a longer one FSG3014 for UK racks. Oz racks are shorter in rack travel than UK Mk2 on, ours are a short version of a Morris 1100 rack.
There is also a longer boot kit for the Morris 1100 rack which may fit yours. Not sure of part number.
I have found a cable tie on the end of the boot is less likely to rip the boot than the original steel clamp and screw.
re the Karcraft numbers above, I also looked on John Smidt's online shop
www.minikingdomonline.com.au and couldn't find his rack boots. I'm sure he has them in stock though.
