Some Graham Phantom Concerns.

Hello friends,

I bought a Phantom I tonearm & was reading the manual few days ago.
I have a concern on page 5, the part it says about tracking force.
It says the std counterweight will properly balance cartridges weighting between approx 4 and 7 grams.
My concern is my shelter 501 weights 8.1grams while my other cart has a weight of 11 grams.
Do I need to purchase the auxiliary counterweight adaptor for these two carts to work ? or am i missing something here ?

my 2nd concern is the bolts that mounts the Phantom base to the tonearm base. Does Graham supply these bolts or does the manufacturer of the turntable supply the bolts ?

THanks for the help.
