not too sure if the 406 hdi box is exactly the same as the 306 one, but i cant imagene it would be very different. you will need a donar xud gearbox to swap the puller mechanism over to the hdi box, fairly simple to do
if you want a quick box with a slightly longer 5th gear, have a look into a 405 dturbo gearbox
