First I am beleiving that the shown order of parts is correct in the picture.
I am still unclear if part 7 goes in with the cupped side facing the piston or or away. From what I gathered the cupped side does in fact face to the left in the picture and is actually inserted into the recess of part 6.
Correct?
IF that is correct, I have tried to install the components into the mc bore and cannot get the assembled components to compress deep enough to get the snapring in.
There are 2 grooves in the bore, a thin one for the snapring(deeper) and a wider groove just before that for the boot.
IF my assembly order is incorrect, please let me know.
If it is correct, please help me get this damn thing in.

SORRY , WRONG THREAD, ....i HAVE BEEN UP ALL NIGHT.
