The bottom radiator hoses are the same, but the 2T hose curves when the 2TG hose is straightish.
If your using the 2T thermo housing on your 2TG, which faces towards the intake (or exhaust- depends which way u bolt it on), you could possibly shorten and use the original 2T hose and bend it over the rocker cover. The problem with this is that you have to drain your radiator fluid everytime u want to take the rockercover off!
The other option is to use the genuine 2TG thermo housing which faces forward, and buy a slightly bent hose from a car store (eg repco). Its best to get the slightly bent hose as a straight hose needs to be slightly kinked.
