Oh and James, you should have changed the 'box while you had the exhaust off... 
Why?
I didn't have a replacement box at the time, and the exhaust had to be changed to pass the MOT / keep me road legal? 
It's no hardship to pop it back off, if/when I change the box 
cant be that torn, as that was the perfect time to convert, with a bit of planning.
Just because you know having the exhaust off would be needed to do the conversion, how do you know all of the other factors (work, family, time, money) that determine whether or not I wish to convert at this time?
Middle of winter with dark nights is hardly a 'perfect' time to convert.
Just because I'm not wanting to do it immediately, doesn't mean I'm 'not that torn' about whether or not I want to do it in the long run.
The fact I had removed the exhaust to change it, is irrelivent. It's hardly a long, or difficult job, is it?
MOT was approaching, I needed to pop a new exhaust on to pass that - not faff around converting a transmission at a time that didn't suit me.
