Would be interested in the aftermarket setup they are using.Looked at another WB today that had a very tidy set up.It bolted up where the plate is for the two flexible hoses. The hoses are for the centre two vents.It had 3 vertical outlets and one horizontal going to the drivers side vent.It was just two neat a fit to be aftermarket. The glove box wasn't touched. would be interesting to find out more about these setups.
