Do a search on the Jeepster board about the aussie locker - you'll get input to install and quality. I don't think there was anything bad about them - just the fit in a scout D44 is a little different I think.
Just ordered mine too. I'm still a little nervous since no-one has tested them long term. But I figure for $200 bones, it's worth a shot.
FYI If you want to buy one, I think the prices go up at the end of the month.
