Rog, sorry I just assumed it was Holden gear - still Tremec? If the 6 spd doesn't have any weaknesses I'd start by testing that out once the car is going. Sounds like your bellhousing and clutch already fit together (same donor car I asssume?), so you're miles ahead with that setup.
There's a saying around here... no photos, didn't happen! Might want to put some "proof" in your gallery mate.
