Carburettor problem

[Bigal23]

So my 1981 2ltr air cooled leisure drive to top has a twin carb set up with a large return Spring attached to the throttle linkage and to the body of the van engine bay. This spring has broken and try as I might can't find anywhere that sells them! Any ideas where I might find one? Unable to read carb manufacturers so little stuck there too!
Any halo/ ideas gladly received
Cheers
Al

The T25 one is unavailable and it should go onto a bracket fitted to the engine.
If yours goes on the body work then it may have had a longer Bay Window one fitted which are still available.
