Intermediate servo question

[Nasty]

I am just pulling out the intermediate servo (134/112) and doing a rebuild
using CK's book and kit. Should there be more to this servo assy than the 134 cover, 112 piston, cushion spring w/large washer like retainer and of course the long "pin". There are no other parts in there, no inner servo spring, inner piston or anything. Is this normal, or do I need to find some more parts.

Thanks

That's all their is to that servo if I'm not mistaken.
