I need to take my DISA unit off to fit the replacement part I bought. It's a T40 I need on a torque wrench as far as I'm aware. Where can I get one for cheap - or even borrow? Located in South West London.
You don't need a torque wrench!! You just need a Torx or Star shaped bit.

Thanks very much. Don't suppose you have a link or something - I'm not sure which set on Halfords it is? http://www.halfords.com/webapp/wcs/stores/servlet/SearchCmd?srch=t40&department=all&action=search&storeId=10001&catalogId=10151&langId=-1
