XRAY - Model racing cars

i purchased a nt1 '09 kit from amain hobbies and i am short some o'rings for the shocks,
only 4 orings were in the shock bag,why? i want to use 2 per shock as shown in diagram.
also the front shock springs seem to short for the aluminum shock body,the collar has to be threaded all the way to the bottom of shock body just where the threads run out,otherwise the spring will flop around loose,the rear shocks/springs are fine.
i am building them as non adjustable with 2 hole piston front and 3 at rear with kit shock oil.
am i doing something wrong?
i followed the manual precisely.
thanks much.

thats all the orings you get, if you want to use two seals in each shock then you need to buy more.
set the spring pre load once mounted to the car winding the coller down as you have toe cars ride height will be way too much
