Volvo Penta (Bosch) Distributor Springs

[parkertyme]

I need timing advance springs for my Bosch 855712 (0231178019) Distributor. It is in a volvo 4 cyl 250A (AQ151A). Does anyone know where I can find these or the part number ? Any help or advice will be greatly appreciated. Ron

you can't just swap the springs, the Dist. needs to be put in a machine and be set by someone who knows how to do it. The shop doing the setup should have springs.
