This is the exact same conversion I am currently doing, CA into 1200 ute. Depending on where you are is who you should speak to about your what to buy list. There is a bloke called Kev Rowley (located 30 minutes west of Brisbane) who is DA MAN IN THE KNOW about putting a CA into a 1200. He has given me a list of what I need right down to part numbers and he sells the necrssary crossmembers and all the other bits you can think of for the conversion. If you want to speak to him let me know and I will PM you his details. He is a very friendly bloke and has a wealth of Knowledge and info on datto conversions.
