Okay, so the ABS is coming off my Fezzy RST.

I'm relpacing the master cylinder with a new non-ABS one and fitting a new servo. The modulators and belts are coming off and I believe there's some in-line valves (or something) to remove. I've heard its under the gearbox cradle? Anyone confirm this?

Also I'm wondering if I need to remove the rear compensator valves? I know these only came on the ABS equipt cars but I'm not exactly sure wether they only work on the ABS systems.

Would there be adverse effects in keeping them on a non-ABS set-up? ie. What would happen when braking and the rear left corner becomes light (cornering)?
Would the braking pressure being reduced there cause more pressure into the corresponding front left brake causing a possible lock-up? Or would there be no effect to the front brake?

I'm not expert , any help/advice greatly appreciated!
