rig car photography equipment

Hi Guys,

I would like to do some car photography in movement using a rig.
I just ordered a Manfrotto 241 Suction Grip with 5/8" Swivel Socket. (http://www.amazon.com/gp/product/B000RTSMWC/ref=ox_sc_act_title_2?ie=UTF8&m=A17MC6HOH9AVE6)

My question is what do i need to buy to connect that 5/8" Swivel Socket (16mm) to my camera ?
ps : i could use my tripod head but i need something between the swivel socket and the tripod head, what is it ?

Thank you very much.

I'm using 2 Avenger suction cups (made by manfrotto) with 3 super clamps and one magic arm.

Two of the super clamps go on the suction cups and one on the magic arm. Purchase or make a long sturdy boom that the super clamps on the suction cups will hold and then place the magic arm on the end and the camera on that.

Just putting your camera on the suction cup and sticking that on the car will not give you very good angles of the car.
