The gearstick has been put back in the wrong way if its hitting the handbrake- take it back and get the garage to take the gearstick out and fit it the right way round.
Do they have a slight angle on then? its my friend whos done it, hes never worked on one of these before, so i dont wanna be funny about it.
is it much of job do you know mate?
You can actually re-fit it yourself, mate. Unscrew the gearknob, pull up the gaitor and you should see some 10mm bolts (I think?) Undo these and pull out the gearstick and put it in the right way. The gearstick should lean towards the driver when in netural.
