i got the apex seals and springs already and my housingsa and rotors are still good. if i buy the above am i good to go???

 

You COULD get away with it. However, personally - i wouldnt rebuild an engine without replacing the following:

corner seals springs and inserts
side seals springs and inserts
front and rear eccentric gear needle bearings.

you also need to inspect:

main bearings
oil control rings and rubbers
eccentric shaft & pilot bearing
oil pump
rotor bearings (shouldnt need doing)

apart from that you should be good

 

...look at the pickture and think about the question that you just posted...do you really think that you are ready to tackle rebuilding an engine?
