Info from nNovia
 

Hi Mike,

It looks like you are getting good advice from the clan. I've attached our catalog that has some pictures that might help. If you could send me a picture of the Canon wireless plate you are thinking about, I can ask the wizards in the shop if they can recommend a solution. Sometimes they will do it for you. They like the break from performing minor miracles all day. My email is harn at nnovia dot com. My best, Harn Soper, nNovia.

thanks Harn...but this thread is from April.
