no L-plate for 5dII + WFT-E4A II?

I can't find any vendor with an L-plate that will work with the 5dII fitted with the WFT-E4A Mark 2 file transmitter. The closest thing I found is the RRS plate for the 5DII and WFT-E4A Mark 1 file transmitter. Will this plate work with the newer file transmitter? Stated differently, are the mark 1 and mark 2 transmitters physically exactly the same?

Are there any other vendors offering the plate I need?
