From what I can ascertain at the present moment is that the attachment is to the LT230 and the syncro adaptor, so potentially should be viable for the 6HP. I take it the gearbox and LT230 are supported as one.
They sent me back a message -
"Hi. This will suit the lt230 and 8hp if it’s the 4wd variant. I’m unsure if the D2 chassis rails are the same width as the defender but could supply the 4 weld on chassis tabs in extra length for you to cut down to suit. Thanks"
Have replied with the chassis dimensions of the D2
Attachment 189281
