XRAY - Model racing cars

i have just purchesd a t1r, it came with these replacement parts, carbon chassis, and carbon shock towers. my problem was this, after spending a couple of hours dismantling and rebuilding the kit on the carbon chassis, and installing my electrics,i realised that my battey cells would not fit. i had to use the standard plastic posts and battery clamps,which do not line up on the carbon chassis.
ive had no luck in sourcing a pair of carbon clamps and the alloy posts. So the car is rebuilt as standard.
anyone know where i can get these parts? i have tryd ebay and my local modelshop with no joy
