Got it sorted in the end. I cheated and ended up using a local bloke from Mobile Thread Works (http://mobilethreadworks.com.au). Highly recommended.

Thanks again all for your help

Thanks for the feedback. Did you notice any increase in power? I got close to to a ten percent increase on the dyno (the graph is posted on the RB30 thread) and noticed it straight away on the road. Economy was way better as well. I removed the heater grid under the carby, smashed out the centre and refitted it.
I have also found the snorkel lets the engine breathe better, too. I block off the pre-heat flap vacuum line with a ball bearing during the warmer months, which also aids economy.

Noticed more power, especially on long highway inclines.

The heater grid i assume has been gutted as the plug was not plugged in when i bought it. I'm having issues with the carby at the moment so will no doubt need to remove the carby soon.. I'll check then!

I'll suss out the pre-heat flap vacuum line once I have her running well again, tapped the top radiator hose while checking voltages on return fuel solenoid last night and the plastic pipe fitting broke off the radiator
