Hi
I use one fan switch for the dash fan and the other one is for the heater, its under the back seat.
The heater under the back seat is from the rear of a Toyota Troop carrier and blows up the factory heater channels.
When I got the news that the transmission was in good shape I decided that I had some spare cash to buy the Quaife.
I had a Quaife in my 1302 and it worked fine, I know that they are not the ultimate but they don't have any handling vices.
The Porsche gearbox guy was saying that they used a lot of things keep them quiet, dual mass flywheel and blankets over things, apparently the blanket over the transmission used to soak up oil and catch fire
