finally got my butt into gear and hoooked up the mk3 fans to the mk4 air channels and all is working sccchhewweeettt.
i had to fibreglass over some chicken wire to make a lip for the air ducts supplying the window with air as this was flush, then i cut some lengths of leather (as i had an old tatty hide wasting away in the garage) and wrapped the around my fibregalss lip and around the mk3 fan unit silicon sealed the overlap and cable tied it around the fan unit and the fibreglass lip.
i had one small mod to make to the mk4 heater controls as the dial for choosing where the air blow from wouldnt select the window option as it didnt retun the metal cable all the way, so i had to space the end of the sheath surrounding the cable a little furhter back from the actaul mounting point, fixed it in position and roberts your mothers brother. so dash is in for good now, heaters work, clocks working with no flashy christmas lights blinking at me.
jobs left to do are: cover the back of the exsposed glovebox, screw some more anchors to the sides of the dash and screw to mk3 dash support to fasten the dash down good and proper so no vibrations whilst driving, make a cusotm steering colum surround out of cardboard and wrap in leather or cloth,fix my head unit wiring as i have now somehow not got the 12v supply when ignition is turned on. after these little jobs the conversion should be completed.
