Brake relay torsion spring (p/n 812 721 191B)

[g4quattro]

I'm looking for the torsion spring which is part of the brake relay mechanism on early (77-83) RHD early Passat/Santana models with brake master cylinder on the left side of the bulkhead. It's item 37 on the pic bnelow.

Alternatively, complete pedal box and/or relay mechanism.

Please send me a PM if you can help, thanks.
