GS 1000 ST carburetor intakes and air box hoses

I need to replace my cylinder base gasket on my GS 1000 ST ( the European and Australian model) and I'd like to take the opportunity to change the carburetor intake rubber pipes and the air box hoses .
The issue is that the carbs are the VM 30s that have an outside diameter of 37.5 mm on the cylinder side and 49 mm on the air box side.
Anyone know where to find parts that would fit as the OEM parts are no longer available?

The stock air box boots, clamps, and inner rings are still available.

And so are the carb boots, clamps, O-rings.

However, these are for the CV carbs.

All of these parts are for the BS 34 carbs not the VM 30 SS:(
The PN should be 13881-49030 and 13885-49030.
The GS 1000 ST was not sold in the USA so there is no chance to find the parts here...
I was wondering if the parts used for the VM 33 smoothbores would not be appropriate?
 
Maybe someone with a loose BS34 carb can measure the outside diameters for you...

Edit: post above showed up while I was typing... How about carb boots for the BS32's?
 
I see now they're the wrong ones, sorry. I bought some of the slide carb type ones from this fella, perhaps you could ask him if he has any more.

Good idea!
I noticed that the GS 850 had the BS 32 carbs.
Now if I could get the outside diameters on these carbs, I would know for sure if they would fit my VM 30's

Just measured the internal diameter of the old airbox to carb hoses from my GSX750ET (BS 32) and they're 48mm.
