GQ TB42s Auto to Manual

[WattsyGQ]

Right, I've made the call to do this conversion. Auto is completely wrecked inside, $4000 quoted rebuild. I have managed to locate a manual box plus "everything needed" to do this conversion for $500.
I'd like to know if anyone has done this and could let me know all the parts I will need so when I head up to get it I definitely know I've got all the bits required!!
Cheers
