2004r rebuild questions

[Skylard]

I'm rebuilding my 2004r and doing update to make it live behind a 455.
my guess it will make around 425-475hp.
I bought a CK master kit with a forward drum, its going pretty good but have a question or two.
When installing the ring that goes on top of the center support,
i see it sits "too far" into the case, the bevel is facing up.
whats the deal?

the kit came with a black anodized servo, the instruction that came with the servo show one typical to the aluminum one on the left. is one better than the other?
i'd prefer to use the one i have and sell the new one from CK.

Cheers!

The servos there need to be separated from the cover and measured there to determine the larger of the two. Looks like you are measuring the inside where the spring goes.

I cant really tell what you have going on there in your pic. Maybe remove flip over and re-install. The bolts do a lot of the holding of the center support and the tight fit of the case.
