As a Canadian I too am subject to the rise and fall of the dollar and have learned to play the shipping game. I am surprised about the shipping time to Oz though as I have bought a few items from down under and shipping was fast. My radio is an X-com which came from there and last winter I sent it back for an update. It was there and back inside of 2 weeks including shop time. I also have a Davies Craig EWP and last year I wanted to upgrade the electronic speed controller to their new one so I actually got it on Australian Ebay new including another pump as a spare at a great price and it was here in a week. Ebay.com now has a global shipping program that simplifies exports for the seller and saves the buyer all the brokerage fees, but it's slow and usually takes about 2 weeks for shipments out of the US. Amazon.ca Prime, on the other hand has it figured out. I see that there is an Amazon.au but it seems that inventory selection is lacking. But have heart because if it is like the Canadian site, then you'll find that they will increase the selection exponentially soon.

Hi Neil;
=C2=A0 =C2=A0I can't confirm for certain = but yes, 2.77" sounds about right.
=C2=A0 After the flywheel= and damper drive modifications to increase clearance, I still only had 1.4= 3" to squeeze it in there, so that is why I also shaved a little off o= f both sides of the rotor cup and also machined a shallow depression into t= he backside of the psru backplate to allow mounting the stator close to the= plate and still have clearance for the windings.
This link will = show a pic of where I measured the 1.43"

=C2=A0 So I would say that you gotta ask yourself whether this is= something that you really want in your own installation and if yes then pu= t that money down on a single rotor/stator and go to work to see if you can= make it work for yourself on your own design.
=C2=A0 Then if you= are as happy with it as I am with mine, you can figure out at what cost yo= u can offer it as an option.
=C2=A0 If I were in your shoes I don= 't think that I would go to the trouble if your only motivation is to p= rovide it as an option for others.
