911 Ventilation front - simplistic set up
 

Guys , i have the normal 76 s front set up but the car is being r-gruppe / back dated as such the engine air blower has gone , heat exchangers gone , flapper boxes gone and now we are at the front.
I want to remove all the vent system excluding the blower to the screen vents AND the centre dash vents , so looking at the system from the front lhs is there a Y tube that you can buy to go from the blower to the two tubes (screen and centre vent?

If there isn't one available a simple PVC/ABS y-pipe from a plumbing store may do it.
