which camera plate for ITE H40 head?
 

anyone know what camera plate setup to use for hd100u? I want to use this camera with an older tripod I have that is extra sturdy. The tripod head, older ITE H40, takes the big plate ie: the length of the plate section on the tripod head is 6 1'2 inches and 3's wide. Not sure if this is standard size or not since it's an older tripod.
thanks
