If you are mechanically inclined you can do the upgrade with an AOD or 4R a lot cheaper than the price of that kit. You can pick up an AOD in the States for around 100 to 200 dollars working, not sure about Australia tho. I already had an AOD that was free to me and rebuilt it with the extra frictions and steels and did all the updates to it. Fab up my own cross member and shorten a 1995 mustang TV cable to fit the 69. Used an aluminum drive shaft from a 2 door 2 wheel drive explorer. I have less than a $1000 in the upgrade. I know your problem tho would be finding the bits and pieces and getting them shipped. Good luck with your upgrade I hope it goes well for you.
