I am very pleased you have cleared that up, and I take your information as positive and constructive.
I was really referring to the Moss Box cars , which I am certain were built on the narrower chassis, which you confirm. If Neil has one of these , then he would have an issue with the wider BTR axle, but looking back through the thread I don't think we know what year of construction his car was.
I did not know the Rover 4 Speeders had the wider 5 speed chassis, but that is another useful piece of information.
Having talked with other Australian owners they try very hard to source parts locally rather than import from Europe, as the freight, import duty and other charges make this a very expensive choice. Thus I was looking for a "home made" solution for him. The BTR axle is pretty bombproof as it was used in the high power version of the Holden Monaro with the 5.7 litre V8. I agree that it would also involve some other changes , all of which would add up, but it still might be his cheapest option, and would almost certainly be the quickest.
