Need Help IDing Servo/Piston etc..

[SSedan64]

Hello,
I bought what was supposed to be a matching Monte SS CZ Valvebody, Governor & Servo. The Valvebody has the purple dye and KZ4 ink stamp, seems to be for a 442 HurstOlds. The Governor looks correct with green gear, small & larger weight + 1 light spring. The Servo cover has 8630569 cast# & Piston has 863?564. Can't read middle # because of the drilled bleed hole.

Does anyone know what this Servo & Piston is from?
And is the KZ Valvebody comparable to the CZ.

I had a link that listed the BR, CZ & KZ automatic shift RPMs. But cant' find it anywhere now.:frown:
Thanks for any help, Todd

It's not the larger 694 cover servo from a GN, so get the GN piece at a minimum or a billet one. Email me if you need one of either.

Thanks Jake, I may do that. I don't know what the heck that Servo or Piston is from. The Monte SS & HurstOlds had the smaller 692.
Is the KZ valvebody about the same as the CZ?

The 569 is one of the smaller ones. I think there is one smaller one. I can't remember. I think I did a post here a coupe of years ago with actual diameters.
The 569 is the generic servo from the low powered cars. Really common.
I mailed about a dozen to Brian Hofer a yr or so ago to use for his stealth servos.
KZ and CZ are similar.
