Mk1 cabrio in line brake regulators - servo & master cylinder upgrade.

My current servo is an 8" with a 20mm master cylinder. I am upgrading to the 9" servo/ 22.2mm master cylinder. Problem is my current rear brake regulator valves are bolted straight onto the master cylinder ( not on the rear axle as is the case on other golfs) Does anyone know if the current regulator valves match up with the bigger master cylinder? Thanks.

yes they will fit, just note if you have your brake light switches here too you'll need some T pieces as the MK2 type MC only has 4 holes not 6
