1967 RHD Barracuda -need help

I have a 1967 Barracuda convertible that was purchased recently. It has no motor or trans and was a six cylinder. The car is a column shift. My plan is to put a 360 in it. What I need help with is on the torque shaft linkage for the 8 cylinder and what tranny to go in it. I am hoping that the Australian Valiant parts will work. I need pictures to start out. If anyone from Australia can help contact me please. I am posting pictures on Instagram and Facebook of the build. Google Ininite custom werks if you care to see the car. Thanks
