Engine Compartment Blower Hose, L&R Where to Buy Options

[NARP74]

I borrowed this pic from @skota23 in another topic. Does anyone know where to buy the hoses like this? I have seen and tried others but they have issues and I wanted to try these.

interesting observation by dr. 914 of auto atlanta.

about mid 75 cars on getting the twin hose set up.
the dr. would know. his chronology is likely 100% correct.

that may have been the case. i'm down here and there is only really a handful of 914s in north antarctica so i don't really see first hand what various reliable examples were.

certainly i have seen various 75 1.8s that had the single fan and hose as part of our L jet research from a couple of years ago.

again the PET does not reflect this. typical really of the PET.
i'd trust dr.914 over the PET on this type of stuff.


EDIT
had a quick scan through the stuff i had on file for 75 L jets.
after looking closely my file agrees with the doctor.
all the ones with vin stickers up to 12/74 are single hose. (most cars have split orig hoses or aftermarket replacement).
all the ones with vins after 12/74 have twin hoses with twin tube transition.
hoses in similar condition. anything original was split around the corrugations.

so much for the PET!

i recall now i even looked for them in south africa. SA had its own VW plant and made 411/412s for the domestic market there. couldn't even track them down with VW parts suppliers there armed with the VW part numbers. searched all the classic bus websites because they had the same fans and ducts. all they had were the corrugated card with aluminium lining aftermarket hoses. i even tried porsche australia because i knew the 912E had them too but the lengths would have been wrong. narthing with them. all they could offer were the corrugated cardboard type heater hoses that the 911s use.
