Thanks mate, Yep that's them. Once converted to AUS dollars and shipped they will be about $650 to my door - just for the brackets.
Thanks for sharing the info - I can see this being a very expensive project ! :oops:
Not having any luck finding these parts available on the sites mentioned. All seem to be out of stock.
Anyone had any luck purchasing the 68802-60070 and 68804A-60070 brackets online ?
