1968 C-6 D Servo?

[x-codegtcs]

Anyone willing to shed some light on a D servo in a C-6? I have found some info, but very little. I am mostly concerned about how it compares to the H servo. Thanks!

Looks like the series code applies to the ratio of the piston and seals. A D looks like a mid range one from this old post I had stored, many of the other links in it are long dead...

Thanks. So as I read it, the D is two steps down from an H in terms of "agressiveness". I know that the servos can be changed with a bore - so this info is very handy.
